【Look! Our cutting-edge technology] Your skin will alarm! The secret of the "immune alarm" is revealed Guangming Daily, Beijing, March 16 (Reporter Deng Hui) How does local infection trigger a systemic immune response throughout the body?
The brand-name water purifier purchased for 5,800 yuan did not bring convenience but only added trouble. The Angel water purifier that Mr. Zhu from Jin'an District, Fuzhou City, Fujian Province bought in 2023 has been experiencing frequent malfunctions since January 2025. It has been officially registered and repaired 6 times during the warranty period and has not been resolved. Now there is also a continuous water leakage problem after shutting down. Seeing that the warranty period is approaching on March 26, 2026, the old man wanted to replace it with a new one but was asked to pay more by the manufacturer. He was in trouble in safeguarding his rights.
After 6 repairs, the water purifier still shuts down and keeps pumping out water. Picture provided by interviewee
What happens to the elderly: If the water purifier cannot be repaired, the warranty period is about to end and it is uneasy
In 2023, Mr. Zhu spent 5,800 yuan to purchase an Angel water purifier at the Angel flagship store in Xiyingmen Building Materials Home Plaza, Jin'an District, Fuzhou City. The merchant promised that the product would be guaranteed until March 26, 2026. "Starting from January 2025, this water purifier began to malfunction frequently. The computer motherboard alone was replaced several times, and new problems would appear soon after each after-sales repair." Mr. Zhu told a reporter from China Business Daily Dafeng News. With this time, it has been repaired six times since 2025.
By October 2025, the water purifier has been repaired 5 times
Mr. Zhu said that the current water purifier still has a problem of non-stop water discharge after shutting down, which seriously affects daily use. At this time, there are only more than ten days left before the end of the warranty period. Mr. Zhu has defended his rights to merchants and manufacturers many times, but the problem has not been completely resolved.
Manufacturer's reply: Only core accessories will be replaced free of charge, and there will be an additional fee for replacement with a new machine.
In response to Mr. Zhu’s experience, a reporter from the Chinese Business Daily Dafeng News called Angel Group’s customer service center. After verification, the customer service backend confirmed six official maintenance records of the water purifier under Mr. Zhu’s name, and also recognized that the machine currently has an unresolved problem of shutting down and discharging water.
Regarding the question of whether the repeated failures and repairs of the water purifier are normal and when the problem will be resolved, customer service said that it is indeed unreasonable. "A malfunction occurred during the use of the machine, which we cannot predict at present. The manufacturer has contacted Mr. Zhu many times before but failed to get through. The solution given at this stage is to replace the RO unit and ACF unit for free." Customer service said that if Mr. Zhu wants to replace the whole machine with a new one, he will need to pay additional fees, and the specific amount is not clearly stated.
The maintenance record shows that the product warranty is March 26, 2026
The customer service clearly stated that if the water purifier expires after the warranty period on March 26, 2026, subsequent maintenance fees will be charged normally. She said that she will provide feedback on Mr. Zhu’s situation.
Legal expert: If the problem persists after two repairs, it can be returned or replaced, and consumers have the right to make their own choices
In response to this matter, Zhang Yunguang, a member of the China Law Society, said that according to the "Regulations on Liability for Repair, Replacement and Return of Certain Goods" -
Article 11 If a product is repaired twice and still cannot be used normally within the validity period of the Three Guarantees, based on the repair records and certificates provided by the repairer, the seller shall be responsible for exchanging the product of the same model and specifications for the consumer free of charge or return the product in accordance with the provisions of Article 13 of these regulations, and then recover compensation from the manufacturer or supplier in accordance with the law or handle it according to the purchase and sale contract.
Article 13 During the validity period of the Three Guarantees, if the conditions for exchange are met, the seller shall return the product because there is no product of the same model and specifications and the consumer is unwilling to exchange the product with other models and specifications, and the seller shall return the product; if there is a product of the same model and specifications, but the consumer is unwilling to exchange the product and requires a return, the seller shall return the product and charge depreciation fees for used goods in accordance with these regulations.
The warranty deadline of March 26, 2026 promised by Angel Merchant in this case is legally binding. At the same time, the law clearly stipulates that if the product still cannot be used normally after two repairs within the warranty period, consumers have the right to choose to return or exchange the product, and this right of choice belongs to the consumer. Manufacturers and merchants have no right to unilaterally specify processing methods.
The water purifier involved has been repaired far more than twice, and it still has functional faults and cannot be used normally. Mr. Zhu has every right to ask the merchant or manufacturer to return the product or replace it with a new one for free. Angel's approach of "only repairing but not replacing, and requiring additional money for replacement" is suspected of violating relevant laws and regulations and infringing on the legitimate rights and interests of consumers. Zhang Yunguang suggested that Mr. Zhu can keep all evidence such as maintenance records, payment vouchers, and warranty vouchers, complain to the market supervision department, or protect his legitimate rights and interests through litigation.

The US-Israel war continues, international oil prices soar, and US President Trump is also facing tremendous pressure at home. In order to stabilize oil prices, the United States will temporarily relax sanctions on some Russian oil. Ukrainian President Zelensky is dissatisfied with this.
According to a report by CNN on March 13, Ukrainian President Zelensky and French President Macron attended a press conference together on the 13th. Zelensky criticized the Trump administration for easing sanctions on Russian oil.
He claimed the move could provide Moscow with around $10 billion to fund its war in Ukraine, saying it would certainly not help peace.
Zelensky added: "We hear claims that this is an attempt to stabilize the situation, but in my opinion the logic is completely different. Russia is spending this money on weapons, mainly drones, which are attacking Ukrainians on a massive scale."
According to reports, his remarks reflected growing concerns in Europe that Moscow may profit from the war with Iran as the global economy looks away from Ukraine and towards oil markets outside the Middle East.
Macron sought to reassure Zelensky that "nothing will distract from our efforts in Ukraine" and reiterated France's support for Kyiv.
"Rising oil prices must not be a reason for us to review our sanctions policy against Russia," he said, adding that Moscow was mistaken if it thought a war with Iran would reduce any pressure it faces.
The United States and Israel suddenly attacked Iran on February 28, killing Iranian Supreme Leader Ayatollah Ali Khamenei and other senior officials. Iran struck back hard and blocked the Strait of Hormuz. The war reached a stalemate that continues to this day.
The continuation of the war has affected global crude oil supply, and rising oil prices have also put U.S. President Trump under tremendous pressure domestically. The Republican Party may be abandoned by voters in this year's midterm elections. Since March 9, Trump has been releasing news that the war is almost over.
The U.S. Treasury Department announced on March 12 that it would temporarily relax sanctions on some Russian oil amid recent tensions in the Middle East that have led to rising oil prices.
On March 12, the United States announced that it had issued 30-day licenses to various countries to purchase Russian oil and petroleum products currently stranded at sea. This measure is seen as a temporary policy adjustment to ease the pressure on global energy supply amid tensions in the Middle East and rapid rise in international oil prices.
According to the Consumer News and Business Channel (CNBC), according to the license text published on the website of the U.S. Department of the Treasury, any Russian crude oil products that have been loaded on ships on or before 0:01 a.m. Eastern Time on March 12 can be delivered and sold within the scope of the license. The license is valid until 0:01 Washington time on April 11.
Reuters quoted Fox News as saying that as of March 12, approximately 124 million barrels of Russian oil were stranded at about 30 locations around the world and had not yet been delivered, enough to supply for five to six days.
U.S. Treasury Secretary Bessent said on the social platform X that the measure is a "targeted short-term measure" that only applies to oil already in transit and will not bring "significant economic benefits" to the Russian government. He said that the temporary increase in oil prices is only a short-term disruption, but in the long run, it will still bring huge benefits to the United States.
The Chinese drama market was booming in May.
"Breaking Down" was launched with great force, far ahead of other new works with unparalleled statistics. Song Zuer's return may have given all the domestic entertainment fans a sense of crisis.
So far, the popularity of the show has successfully exceeded 30,000. Looking at this momentum, do you plan to continue to harvest the market?
Unfortunately, the schedule was not coincidental, and it encountered a strong enemy——
"The Legend of Tibetan Sea".
This Machiavellian drama starring Xiao Zhan is the TOP1 most anticipated drama in Mainland China in 2025. Being on CCTV shows its potential to be a hit.
Therefore, the show did not exceed the audience's expectations after it was launched. After only 2 hours of broadcasting, the peak ratings easily exceeded 2, which is quite impressive.
However, this report card is not only due to Xiao Zhan's top popularity, but also to the fact that the play itself has a level that exceeds that of works of the same type.
After watching 2 episodes in one go, I just want to say that this is the drama king of the year in 2025!
So what’s so good about this show?
01 Top quality, gripping plot, classic Machiavellian flavor
"The Legend of Zanghai" tells the story of Zhinu (played by Xiao Zhan), the son of Zheng Kuaiduo, the eunuch of Qintian Prison, who saw his family being exterminated with his own eyes, and a seed of hatred was planted in his heart.
After ten years of hard study, he changed his face and became "Zanghai". He rose to prominence in the court by virtue of his construction skills and manipulation skills, and finally revealed the truth about the family's annihilation.
To make a good Machiavellian drama, the director must not only be clear about what he is filming, but also make it understandable to the audience.
Although the story background of the play is complex, it has a clear structure and distinct characters. The highlights can be summarized in three words.
The first word: suspense.
Ten years ago, the hero's father, Kuai Duo, pretended to be a Buddhist monk, but secretly dug more than a thousand feet underground until he unearthed an ancient tomb.
Several workers died mysteriously, and all the soldiers in the tomb were dispatched.
Kuai Duo grabbed a "green rock" at the last moment, and the scene was completely dark. What happened?
As soon as the camera turned, news came from the capital that the Fengchan Tower collapsed and no one survived.
However, Kuai Duo hurried home late at night, and before he could speak, the whole family was surrounded and suppressed by Lu Yin of Pingjin Houzhuang.
It was obvious that he was here for the mysterious ancient jade.
For this thing, he did not hesitate to cover up people's eyes and let the Fengzen Tower, which was finally repaired, be destroyed. One can imagine the wide involvement behind it.
And although it is a plot drama, the plot involves tomb exploration adventures and feng shui manipulation, which adds to the suspenseful atmosphere of the plot and makes people more and more fascinated by it.
The second word: tragic.
On this night, more than ten members of Kuai's family were killed. Only Kuai Duo's son, Zhinu, escaped because he hid in a secret passage.
At a young age, he watched his relatives die tragically.
And the words "live on" that his father silently said before he died have become the only belief in Zhinu's life.
In this scene, the audience can truly feel the director's shooting skills.
Even if a young apprentice pretends to be a child slave in order to repay a favor, it is extremely touching.
A sense of tragedy hit the face, and the audience could truly feel the hero's heart-wrenching hatred.
The third word: revenge.
Since the previous part was quite heavy, the atmosphere of the plot eased as the male protagonist grew up.
At that time, the child slave had changed his name to Zanghai, and was learning skills from his masters. Finally, he came back to Beijing for revenge.
Of course, the feeling of satisfaction can only appear in the later stages. The so-called development of a male protagonist requires more experience and setbacks.
When Zanghai first entered the capital, he realized that people's hearts are sinister, crouching tigers, hidden dragons, but isn't he just a lurking dragon in the abyss?
Just waiting to accumulate a lot of strength and give the enemy a fatal blow.
It can be said that Zheng Xiaolong is the only one who can capture the machinations with such quality.
The level of "The Legend of Tibetan Sea" is definitely not inferior to those classic works, and the addition of actors also provides a lot of blessings to the drama.
02 All the actors are talented, Xiao Zhan is so amazing
This new work has a strong cast, and not a single actor is cast for free, making the characters flesh-and-blood and vivid.
First place, Xiao Zhan.
To be honest, I was worried that Xiao Zhan wouldn't be able to sustain such a heavy story at first, but I didn't expect that his acting skills would improve so much.
For example, under the test of the masked benefactor, he seemed to casually tell the details of the family's destruction, but in fact his eyes had an undercurrent, as if containing overwhelming hatred, which immediately created the tension of the character.
Moreover, Xiao Zhan's costume style is a major advantage in itself. It is rare to see such a good-looking and capable young man.
Just choose him.
The second place is Zhong Hanliang.
I didn't expect that Chung Han-liang would one day play the role of Xiao Zhan's father, but the Kuai Duo he played in the play was so upright, with a mustache, his mature, steady and gentle temperament was even more obvious.
At Chung Hanliang's age, he is actually suitable for playing some high-quality roles.
Before dying, the scene where Kuai Duo looks at his child can be regarded as the highlight of the whole play. The silent lines express his despair for fate and reluctance to let go of his son.
It seems that Zhong Hanliang has already entered the camp of the Mesozoic powerful faction without knowing it.
The third place is Chen Yanxi.
After the divorce, Michelle Chen seemed to be cheating. There was the tolerant and intelligent wealthy lady Kaisi Chen in "Dear Enemy" before, and later there was the gentle and powerful Zhao Shangxian in "The Legend of Hidden Sea". Every new role can be deeply rooted in the hearts of the people.
But I still prefer the latter role, because Chen Yanxi played the strongest side of an ancient woman. In order not to drag her husband down, she risked her life to resist. Her weak and tough figure made people's eyes red.
Although she is a supporting role in the play, I think Michelle Chen has become the heroine of her life.
The fourth place is Huang Jue.
Huang Jue is also recognized as a capable actor, but he has a wide range of roles, and he can be both good and bad.
In the new drama, he plays Zhuang Luyin, a villainous boss with a compelling aura. He doesn't need to put on a show, and his characteristics of being calm, self-confident, and vicious are all there.
From the perspective of the male protagonist, facing such a powerful enemy, one really needs to be careful every step of the way.
In addition, the performance of the young flower Zhang Jingyi was also good, performing the "white and black" attributes of Xiang An Tu.
There are also actors familiar to the audience such as Yu Nan, Zhang Guoqiang, Qiao Zhenyu, Bai Bing, etc. who will play important roles. The lineup looks like a masterpiece.
03 Conclusion
We do not deny that inviting a popular actor to serve as the male lead in "The Legend of the Hidden Sea" is a risky move.
But times have changed. If domestic costume dramas want to attract people, sometimes they have to bow to traffic.
And this is not a bad thing, it all depends on what kind of popular actors the director chooses.
A young man like Xiao Zhan who has his own popularity and can hold up the role is still worth betting on.
As long as the script can support the film and the actors can stand up to their roles, there will be no need to worry about no one watching.
Therefore, the popularity of this new work is actually within the expectations of the audience, but whether it can go further still depends on the subsequent plot and acting performance.
I believe this drama can inject new vitality into the Chinese drama market and add another benchmark for the Machiavellian theme.
So what do you think about this?
IT House reported on March 17 that at the 2026 GTC held early this morning, NVIDIA founder and CEO Jensen Huang delivered a keynote speech, calling on global companies: they must seize the opportunity of the current explosion of AI agents and formulate their own "OpenClaw strategy."
Any company in the world today needs to have its own OpenClaw strategy, a strategy for an intelligent system, which is the new computer.
Jen-Hsun Huang highly praised OpenClaw, an open source AI agent project that has set off a craze around the world. Although its founder has been poached by OpenAI, OpenClaw will continue to exist and develop as an open source project.
Jen-Hsun Huang said: "OpenClaw allows us to create personal intelligence, and the significance of this is incredible." He further pointed out that OpenClaw "provides what the industry needs most when it needs it most."
To illustrate the potential of OpenClaw more vividly, Huang compared it with milestones in the history of PC development. He believes that OpenClaw is to artificial intelligence what the Windows operating system is to personal computing.
In addition, he compared it to influential technologies such as the Linux operating system, Kubernetes cloud projects, and HTML. Huang Renxun explained: "It allows the entire industry to seize this open source software stack and do various innovations based on it."
While praising OpenClaw, Huang Renxun also pointed out a major challenge in its application: security. To this end, NVIDIA announced the launch of its own version based on OpenClaw - NemoClaw. The product allows users to add privacy and security controls to their AI agents.
"It has a network guardrail and a privacy router, so we can protect these 'claws' and prevent them from executing instructions at will within the company, so as to achieve safe operation," Huang explained.
In order to promote NemoClaw, NVIDIA held a special "Claw Making" event during the conference, allowing participants to develop their own customized AI agents.
OpenClaw founder Peter Steinberg said: "OpenClaw brings people closer to AI and helps create a world where everyone has their own intelligent agent."
In addition to releasing strategies related to OpenClaw, Huang also announced a number of major news on the first day of GTC, including the launch of a new inference system integrated with Groq technology. Previously, Nvidia had reached a $20 billion deal with the AI chip startup. At the same time, Huang Renxun predicts that the market demand for its Blackwell and Rubin AI chips will reach US$1 trillion by 2027.
2026.2.18 Real-time Gold Quotes: Domestic market closed, international rebound! How to go after the festival? Buy the dip or wait and see?
On the second day of the first lunar month of the Year of the Horse in 2026, the gold market showed a differentiated pattern of domestic closures and international rebounds. Many people are concerned: Is it worthwhile to buy gold now? Will it rise or fall after the holidays? This article explains the real-time gold price, reasons for rise and fall, market outlook and operation suggestions for ordinary people at once.
1. Quick overview of real-time gold prices (updated at 12:20 on February 18)
International gold price (normal trading)
- London gold spot: 4924.71 US dollars / ounce, +66.73, +1.37%
- COMEX Gold Futures: $4914.50/oz, +0.38%
Domestic gold price (market closed, maintaining pre-holiday closing price)
- Gold T+D: 1108.5 yuan/gram, -16.55, -1.47%
-Shanghai gold main company: 1110.1 yuan/gram, -18.16, -1.61%
- Bank investment gold bars: 1109–1134 yuan/gram
- Retail price of pure gold in gold store: 1480-1560 yuan/gram
- Gold recycling reference: about 1060-1083 yuan/gram
The domestic market will be closed from February 14th to February 23rd, and normal trading will resume on February 24th; international fluctuations during the holiday will directly affect the opening after the holiday.
2. Why does the gold price diverge today?
- International rebound: The US dollar weakens, low buying orders enter the market, and risk aversion sentiment rebounds slightly
- Domestic static: The market is closed during the Spring Festival, and the price stays at the pre-holiday closing price
- Short-term pressure: The Fed's expected interest rate cut is postponed, high profit taking is taken, and the gold price has previously retreated.
3. What do you think of the post-holiday trend?
- Short term (1-2 weeks): The main focus is to find the bottom in shocks. The international focus is on the support of 4800-4850 US dollars, and the domestic support is 1080-1100 yuan/gram; the rebound pressure is 4950-5000 US dollars, 1120-1140 yuan/gram.
- Mid-term: The central bank’s gold purchase supports the bottom, geopolitical risks still exist, the space for deep decline is limited, and the allocation value remains
- Key observations: Federal Reserve policy, U.S. dollar index, situation in the Middle East, post-holiday physical consumption demand
4. A must-read for ordinary people: Gold buying & investment advice
1. Buy jewelry (consumption)
- Gold stores have high quotations and expensive labor costs, so they are suitable for just-in-time wear; if you don’t need it urgently, you can wait for the post-holiday sales, which is more cost-effective.
2. Investment in gold bars/accumulation funds
- It is inconvenient to operate when the market is closed. It is safer to open positions in batches after the holidays. Do not chase high prices or place heavy positions.
3. Gold recycling
- The reference price is 1,060-1,083 yuan/gram. Hurry and choose regular channels. Pay attention to deductions and quotations.
4. Leverage trading (T+D/futures)
- There is a high risk of gapping during the market break. If you are light or short position during the holidays, beware of the risk of opening price difference.
5. One sentence summary
The domestic market is closed and there is no operation, and the international rebound has bottomed out; after the holiday, we will first look at stabilization before making arrangements. Buy jewelry and other promotions and investments in batches, stability is king.
Tip: The gold price changes in real time. The data in this article are for reference only. Transactions are subject to the disk and store quotations.

Your skin will sound the alarm!
The secret of the 'immune alarm' revealed
Guangming Daily, Beijing, March 16 (Reporter Deng Hui) How does local infection trigger systemic immune response throughout the body? A joint team composed of Professor Liu Wanli from the School of Life Sciences of Tsinghua University, Professor Zhang Yonghui from the School of Pharmacy, and domestic experts from many fields have recently solved this immunological problem after more than ten years of scientific research. Research has found that the metabolic intermediate in skin fibroblasts, farnesyl pyrophosphate (hereinafter referred to as "FPP"), can transform into an "immune alarm" at critical moments, activating two signaling pathways to enhance systemic immune responses. Relevant research results provide new targets for the development of new vaccine adjuvants and the prevention and treatment of autoimmune diseases such as systemic lupus erythematosus.
The skin is the first barrier against pathogen invasion and environmental stimulation. Local infection or injury lesions are like "beacons" in the immune system, accurately transmitting danger signals to the entire body and mobilizing systemic immune responses. The mechanism behind this process has always been an unsolved mystery in the field of immunology. The answer to this question will not only deepen the understanding of the regulation of the immune system, but also be related to the analysis of the pathogenesis of autoimmune diseases such as systemic lupus erythematosus and the optimization of clinical intervention strategies.
In order to solve this problem, the joint team focused on the key metabolic network of the mevalonate pathway and gathered multidisciplinary forces such as immunology, metabolomics and systems biology. After more than ten years of systematic research, they finally identified and confirmed the "key messenger" in this pathway that transmits immune signals from local lesions to the whole body - FPP.
Research shows that FPP can serve as a key messenger linking local inflammation and systemic immunity, regulating biochemical center reactions and amplifying systemic humoral immune responses. Simply put, when the skin is infected by bacteria or exposed to strong ultraviolet rays, the skin's keratinocytes will initiate an emergency response, causing FPP to rapidly accumulate in the cells.
"This substance is an 'immune alarmin' emitted by cells. It will precisely bind to the intracellular domain of TRPV3 on the cell, just like a key opening a lock, allowing calcium ions to enter the cell, thereby activating two signaling pathways and prompting the cells to secrete two key substances, IL-6 and CCL20." According to team members, the two substances have a clear division of labor: the former can promote the differentiation of immune cells, and the latter recruits and promotes the movement of dendritic cells to lymph nodes. The combination of the two can significantly enhance the immune response of lymph nodes, not only allowing the body to produce more antibodies that can fight pathogens, but also forming immune memory, allowing the body to respond quickly the next time it encounters the same type of pathogen.
The team also found that aromatic substances in plants such as carvacrol and camphor can also enhance immunity through the same signaling pathway, which also provides scientific basis for the traditional saying that "aromatics ward off dirt".
"In the future, we will continue to delve into the details of this signaling pathway and explore its role in other immune diseases." Team members said that they will accelerate the clinical research of related adjuvants and targeted drugs, and explore more natural immune regulatory substances in combination with traditional aromatic Chinese medicine, so that the results of basic research can be truly transformed into clinical diagnosis and treatment solutions.
【Knowing is by my side】
Why basking in the sun is good for your health
Many people know that "more sun exposure is good for good health", but few people know the reason behind it - in fact, the essence of sun exposure is to "recharge" our immune system and enhance resistance.
The skin is the body’s largest “protective wall” and an “early warning station” for the immune system. When the skin is exposed to sunlight, it will produce an "alarm molecule" called farnesyl pyrophosphate, which sends an "alarm" to the body like lighting a beacon. Subsequently, a "channel" (TRPV3 channel) on the skin cells will open, and extracellular calcium ions will penetrate into the cells in large quantities, allowing the body to release substances that can speed up and strengthen the immune system, and the resistance will naturally increase.
However, don’t be greedy for too much sun exposure: Moderate exposure to the sun can gently activate the immune system and improve protection; however, exposure to too much sun for too long or too hard will cause the immune system to “overload” and cause inflammation, which may actually aggravate some autoimmune diseases (such as lupus erythematosus). The immune system itself of such patients is too “active” and will mistakenly attack their own body organs. This also just confirms what our ancestors said about the "golden mean". Too much is never enough, and immunity also needs to be balanced.
