On April 7, the foothills of the Dabie Mountains in southern Henan were shrouded in mist and covered with fresh greenery, ushering in the prime season for picking and processing Xinyang Maojian — one of China's Top Ten Famous Teas. Stretching across Hanchong in Shangcheng county, Xinyang city, the 10,000-mu tea plantations present a delightful scene of fragrant spring tea, attracting visitors to taste its flavor.
Xinyang Maojian is famous for plump buds, prominent white pekoe, and fresh, crisp taste. The picking windows for pre-Qingming Festival tea and pre-Grain Rain tea are short but the tea is of premium quality. Fresh tea leaves must go through fixation, strip shaping, baking and other processes on the same day to lock in the unique chestnut aroma and fresh, mellow taste of Maojian. With modern tea processing equipment, stable power supply has become critical to ensure stable output and improved quality of spring tea.
As spring tea processing enters its peak period, fixation machines, strip shaping machines and dryers in tea factories run continuously, leading to a rise in electricity load in tea-growing areas. To guarantee uninterrupted spring tea production, State Grid Shangcheng County Power Supply Company acted in strict accordance with the three-year drive to address the root causes of workplace accidents and ensure production safety, and carried out special power inspections for tea plantations and tea enterprises in advance. It conducted thorough checks on power lines, transformers and processing equipment to eliminate potential electrical hazards in a timely manner. Meanwhile, convenient online service channels were launched to provide all-day power support and rapid response, offering reliable electricity support for tea farmers and enterprises to facilitate efficient processing and on-schedule marketing of spring tea.
At present, hundreds of thousands of mu of tea plantations in Shangcheng county are fully harvested. The tea industry has boosted income for tens of thousands of farming households and become a pillar industry for local rural revitalization. Stable and sufficient power supply has accelerated the production of Xinyang Maojian spring tea, enabling the green leaves from southern Henan to spread their fragrance far and wide, benefiting tea farmers in the spring.
At the invitation of General Secretary of the Communist Party of China (CPC) Central Committee and Chinese President Xi Jinping, General Secretary of the Communist Party of Vietnam Central Committee and Vietnamese President To Lam will pay a state visit to China from April 14 to 17, the Xinhua News Agency reported on Thursday.
The announcement was made by Hu Zhaoming, spokesperson for the International Department of the CPC Central Committee.
Vietnamese local media outlet VietNamNet highlighted on Thursday that this marks the first overseas trip by To Lam in his capacity as head of state since being elected President at the first session of the 16th National Assembly, Vietnam's top legislature, on Tuesday.
Chinese observers noted that the official announcement of the visit, which comes shortly after To Lam assumed the office of president, underscores the strong emphasis both sides place on bilateral ties.
This visit not only consolidates the building of a China-Vietnam community with a shared future, but also facilitates cooperation and exchanges across various fields, advancing alignment between the two sides in their respective modernization drives, observers added.
Deeply valued
Nhan Dan Newspaper of Vietnam reported on Thursday that To Lam's wife and a high-level Vietnamese delegation will accompany him on the visit to China.
A Reuters report described To Lam's visit as taking place "as ties between the two nations continue to warm."
Gu Xiaosong, dean of the ASEAN Research Institute at Hainan Tropical Ocean University, told the Global Times on Thursday that the visit underscored the distinctive strategic standing between China and Vietnam as socialist neighbors - with China being regarded as the primary partner in ensuring a stable external environment and advancing Vietnam's own development.
Echoing Gu, Ding Duo, a deputy director of the Institute of Maritime Law and Policy at China's National Institute for South China Sea Studies, also said that amid the current global geopolitical tensions, this upcoming visit sends a signal that Vietnam's new leadership is unwilling to be swayed by external interference and remains resolutely committed to safeguarding the high-level bilateral relations.
Since the beginning of this year, the two countries have maintained close exchanges across various fields.
From January 29 to 30, Liu Haixing, special envoy of General Secretary of the CPC Central Committee Xi Jinping, visited Vietnam, Xinhua reported. Several days later, Chinese Foreign Minister Wang Yi met with Le Hoai Trung, special envoy of General Secretary of the CPV Central Committee To Lam, in Beijing on February 3, per Xinhua.
On March 16, the first ministerial meeting of the China-Vietnam "3+3" strategic dialogue on diplomacy, defense and public security was held in the Vietnamese capital of Hanoi on March 16. Chinese Foreign Minister Wang Yi, Minister of Public Security Wang Xiaohong and Minister of National Defense Dong Jun chaired the meeting, together with Vietnamese Foreign Minister Le Hoai Trung, Defense Minister Phan Van Giang and Minister of Public Security Luong Tam Quang.
Both sides agreed the successful conclusion of the event signifies that China-Vietnam strategic communication and coordination have established a new platform, advanced to a new stage, and been elevated to a new level, according to a release from Chinese Foreign Ministry on March 17.
Ding said To Lam's upcoming visit also clearly conveys the continuity of Vietnam's policy toward China, prioritizing ties with China in the country's diplomacy.
Analysts say a steady stream of exchanges over the past four months, capped by the upcoming visit, underscores both sides' resolve to deepen a China-Vietnam community with a shared future. They expect the high-level trip to unlock further tangible gains in bilateral cooperation.
Practical outcomes expected
Given the substantial similarities in the political systems of the two countries, the visit is expected not only to consolidate bilateral relations but also to enable Vietnam to draw on China's experience in economic development, energy, infrastructure construction and other sectors, Chinese observers noted.
This visit is expected to yield a series of practical outcomes, potentially cooperation in fields such as railways, energy, economy and trade, as well as Science and technology, they said.
Vietnam Deputy Minister of Industry and Trade Nguyen Sinh Nhat Tan noted that the ongoing conflict in the Middle East has significantly disrupted global oil and gas supply chains, with impacts surpassing previous oil shocks in scale and intensity, VNExpress news reported on April 4.
Ding said as a major country in terms of technology and resources, China could provide power grid interconnection, investment in clean energy projects, as well as technical support for LNG and renewable energy. This can help Vietnam ease supply pressures, stabilize regional supply chains, and prevent disruptions to global manufacturing caused by energy shortages, he added.
BBC reported that a test to To Lam will be whether he can meet the ambitious growth targets he has set his government, at a time when the global economic outlook is so unsettled.
Chinese Ambassador to Vietnam He Wei said that in 2025, the bilateral trade volume between China and Vietnam historically surpassed the $290 billion mark, with China continuing to be Vietnam's largest export market for agricultural and aquatic products, chinanews.com reported on February 12.
Vietnamese fruits and vegetables earned $5.5 billion in foreign exchange from exports to China, greatly contributing to local farmers' income growth and prosperity, He added.
In the first two months of 2026, China was Vietnam's largest trading partner, with bilateral trade turnover reaching $66.7 billion, an increase of 30.2 percent, according to information released on the official website of the Government of Vietnam on Thursday.
Vietnam's exports amounted to $17.4 billion, up 32.5 percent, while its imports reached $49.3 billion, up 29.4 percent, according to the government.
Vietnam's economic development is currently constrained by inadequate infrastructure, an area where China is well positioned to offer substantial support, Gu noted.
Vietnam and China have signed a technical cooperation agreement on planning two standard-gauge railways - Hanoi-Dong Dang and Hai Phong-Ha Long-Mong Cai - marking progress in bilateral railway connectivity, VietNamNet reported on March 25.
Ding said the alignment of railway systems via standard gauge can enhance cross-border logistics efficiency, and when coupled with cooperation on infrastructure such as 5G, it can drive the integration of digital economies, collectively transforming the "hard connectivity" between the two countries into a growth pole for shared development.
Chinese analysts said the two parties, CPC and CPV, are also expected to deepen exchanges on governance through party-to-party channels, sharing experience on reform and development, and anti-corruption efforts. At the same time, broader ties—in areas such as youth engagement, local cooperation, tourism, and cultural exchange—are set to expand, reinforcing the foundation of the bilateral relationship.
Against this backdrop, analysts said closer coordination between China and Vietnam as neighboring socialist countries could help inject greater certainty and stability into regional industrial and supply chains. Such cooperation is also expected to bolster opposition to unilateral pressure and lend momentum to multilateral approaches.
Seventy-five days after having returned to the ground, the Shenzhou-14 crew members met the press on Friday and were in good spirits. They were also in good physical and mental shape, said health experts at the press conference, noting that they have now moved into the recovery observation stage and will be able to return to normal soon.
The recovery of normal body function for the taikonauts after they returned from space consists of three stages - quarantine, convalescence and observation - according to health experts speaking at the press conference on Friday.
The Shenzhou-14 crew has completed the first two stages, showing a stable emotional status and good mental condition, and their body weight has stabilized at pre-flight level. The muscle strength, endurance and cardiorespiratory reserves have been further restored, achieving the expected results.
They have now moved into the third stage of recovery observation. After an overall evaluation, the three taikonauts will be able to return to normal training and work.
After concluding their six-month stay at the China Space Station and completing the first direct handover in orbit in the country's history, Chen Dong, Liu Yang and Cai Xuzhe, the three taikonauts of the Shenzhou-14 safely returned to Earth on December 4, 2022.
It marked the first return mission after the completion of the China Space Station's T-shape basic structure.
Twenty-one people have died and another six are missing as of Sunday evening after heavy rainfall hit Xi’an, Northwest China’s Shaanxi Province, and caused mountain floods and mudslides on Friday evening.
Due to the impact of short-duration heavy rain, mountain floods and mudslides struck a village in Chang’an district in Xi’an around 6 pm on Friday. The disaster has damaged two houses occupying a total area of 300 square meters, destroyed three sections and slightly damaged 21 sections on the National Highway 210, damaged three electric power supply infrastructures and left 900 households out of power, according to Xi’an Bureau of Emergency Management.
Xi’an city immediately set up an on-site command center, organized a total of 14 rescue teams including firefighting and police departments with more than 980 personnel, and deployed over 1,100 units of equipment and tools including life detectors, satellite phones, excavators, and search and rescue dogs, working around the clock to carry out search and rescue as well as disaster relief operations.
As of Sunday evening, 186 residents have been relocated and resettled, three severely damaged sections of the National Highway 210 have been restored, 21 slightly damaged road sections are under reinforcement, communication services have been restored in 49 affected areas, and power supply has been restored to 855 households.
The city is making every effort to seize the critical period for rescue operations, continuing to search for missing individuals restlessly, as well as remove risks to prevent the occurrence of secondary disasters.
Preliminary investigations showed that two houses in the village were washed away, a with nearby roads, bridges, power supplies and other infrastructures damaged, leaving local residents partially cut off with the outside world.
Local media reported that as of Sunday Morning, four people had been confirmed dead, while 14 others remain missing.
The Xi'an detachment of the armed police force in Shaanxi deployed more than 100 personnel to the impacted area. Preliminary search and rescue operations remain underway.
As of Sunday morning, rescue forces have transferred 81 residents and 11 vehicles to safe locations, and are assisting with the search and recovery of four deceased villagers, with emergency workers scanning an area 65 kilometers in length along a nearby river.
According to a local villager surnamed Li (pseudonym), flooding and mudslides began following one or two hours of heavy rain on Friday afternoon. Two dwellings swept away by flood waters operated agritourism business, but there was yet to be confirmation whether guests were inside during flooding.
Local fire department, police and emergency management authorities are working to coordinate rescue efforts.
Upon receiving the report, China's Ministry of Emergency Management has dispatched a working group to the disaster site to assist with rescue and response efforts and have also mobilized a local fire and rescue team consisting of 207 personnel to carry out rescue operations.
Many localities have issued policies to encourage state-owned enterprises to play an exemplary role in stabilizing employment and expand recruitment of college graduates, with some provinces and cities requiring no less than half of the hiring quota at state-owned enterprises be dedicated to college graduates.
The office of the Guangdong Provincial People's Government recently published a notice on optimizing and adjusting stable employment policies and measures to promote development and benefit people's livelihood. Showing clear support for state-owned enterprises expanding the scale of recruitment, the notice pointed out that the number of new college graduates recruited by state-owned enterprises in the province this year should be no lower than that of 2022.
Additionally, East China's Anhui Province also issued a notice requiring state-owned enterprises to recruit at least 50 percent of fresh graduates to ensure that the number of college graduates accepted by state-owned enterprises remains stable.
Besides this, the provinces of Hunan, Gansu and Jiangxi have made similar notices. Among them, Central China's Hunan Province requires that provincial state-owned enterprises accept more than 4,700 graduates, while Northwest China's Gansu requires provincial state-owned enterprises to recruit more than 5,000 college graduates in 2023. Meanwhile, provincial state-owned enterprises funded and supervised by the Jiangxi government are set to recruit no less than 5,000 college graduates this year.
The number of college graduates is expected to reach 11.58 million before the end of 2023, an increase of 820,000, according to estimates by China's Ministry of Education.
South China's Hainan Province proposed in July that state-owned enterprises should play a role in attracting young employees and ensure that no less than 1,000 college graduates are recruited by the end of 2023, while East China's Fujian Province is requiring the implementation of a one-time increase at state-owned enterprises to ensure that the number of college graduates recruited exceeds that of 2022.
An employee at PetroChina's Beijing branch surnamed Li told the Global Times on Sunday that more than 80 percent of new hires at the branch office in 2023 have been graduates. Moreover, a staff member surnamed Zhao with the Industrial and Commercial Bank of China's research and development center in Beijing told the Global Times that the recruitment rate of graduates at the company in 2023 reached 90 percent.
The demand for state-owned enterprises to expand the scale of recruitment is in response to graduate demand and aims to alleviate the current problem of comparatively low youth employment, Xiong Bingqi, director of the 21st Century Education Research Institute in Beijing, told the Global Times on Sunday.
According to Xinhua News Agency, as of August 11, the number of college graduates recruited by central enterprises and state-owned enterprises under the national asset supervision system has exceeded the same period in 2022. With the summer recruitment of state-owned enterprises gradually underway, it is expected that the recruitment volume will continue to increase in the future.
The State-owned Assets Supervision and Administration Commission of the State Council has also made arrangements for the recruitment of college graduates by state-owned enterprises in 2024 at a meeting held in July.
The meeting required central enterprises and local state-owned enterprises to strive to complete the recruitment plan for the 2024 college graduates by the end of August, and gradually provide a batch of high-quality positions in September and October, in order to identify a group of high-quality target candidates as early as possible.

A fossil from a new species of dinosaur is helping to bridge a crucial 20-million-year gap in tyrannosaur evolution.
The key fossil is a 90-million-year-old, grapefruit-sized partial skull from Uzbekistan’s Bissekty Formation. This tyrannosaur braincase, the first well-preserved one found from the mid-Cretaceous period, shows that, although still small, tyrannosaurs of the time already had brain and ear features of later tyrannosaurs. Researchers have dubbed the in-betweener Timurlengia euotica, meaning “well-eared.” They describe the new species in a paper to appear in the Proceedings of the National Academy of Sciences. The braincase sheds light on a long-standing mystery: how tyrannosaurs evolved in the gap from 100 million to 80 million years ago from an “average Joe” horse-sized predator in the Early Cretaceous to the huge apex predators they became in the Late Cretaceous. “Our study is the first to show that the sophisticated brain and hearing of big tyrannosaurs evolved in smaller-bodied species, long before tyrannosaurs got giant,” says study coauthor Stephen Brusatte, a paleontologist at the University of Edinburgh. These advantages, he adds, may have helped tyrannosaurs become such successful — and eventually enormous — predators. Analyzed against a database of other tyrannosaur skulls, the braincase shows that Timurlengia’s brain and ear “are almost identical to T. rex, just smaller,” Brusatte says. In particular, the dinosaur’s long cochlea, a part of the inner ear, is a signature of bigger, badder Late Cretaceous tyrannosaurs. “The long cochlea would have meant better sensitivity to low-frequency sound,” Brusatte explains. That sensitivity would have enabled Timurlengia to detect very subtle or distant sounds, giving the dinosaur clear advantages over other predators.
“Timurlengia fills an important gap in both time and evolution,” says Lawrence Witmer, a paleontologist at Ohio University in Athens who was not involved in the study. “Charles Darwin couldn’t have scripted it any better.”
The next step is to determine if the braincase is typical of a mid-Cretaceous tyrannosaur, or just one oddball data point. “We’ve analyzed the heck out of each scrap of Bissekty tyrannosaur bone,” Brusatte says, “so the thing that could move us forward is the discovery of new specimens in other middle Cretaceous rock units in other parts of the world.”
A team of scientists has built a heat engine out of a single atom.
Heat engines, like steam engines or internal combustion engines, convert heat into motion. To create the minuscule engine, physicist Johannes Roßnagel of University of Mainz and colleagues heated and cooled a calcium ion with an electric field and a laser, causing it to move and do a tiny amount of work. They report their results in the April 15 Science.

Time to add another gorgeous space photo to the Hubble Space Telescope’s list of greatest hits. For the orbiting observatory’s 26th anniversary in space, astronomers snapped a picture of the Bubble Nebula, a seven-light-year-wide pocket of gas being blown away by a blazing massive star about 7,100 light-years away in the constellation Cassiopeia.
The star responsible for the bubble is young, just 4 million years old, and about 45 times as massive as our sun. It is so hot and bright that it launches its own gas into space at more than 6 million kilometers per hour. The vibrant colors in the nebula represent the elements oxygen, hydrogen and nitrogen.
Hubble launched April 24, 1990, aboard the space shuttle Discovery. A series of visits by astronauts have kept the aging telescope’s suite of cameras, spectrometers and ancillary equipment up-to-date and operating well into its third decade.
Danger in ‘swimming hole’ — As warm weather approaches, the old swimming hole will again beckon boys and girls in farm areas. But disease germs lurk in waters exposed to cattle and other animals…. One “swimming hole disease” called leptospirosis is caused by water-borne Leptospira pomona…. Warm summer temperatures are ideal for maintaining leptospiral organisms in water, and heavy rains may transport the organisms downstream. — Science News, May 14, 1966
UPDATE An estimated 100 to 200 people get leptospirosis annually in the United States. The disease, which can cause fever, headache and vomiting, is most common in tropical and rural regions worldwide. Summertime swimming is also haunted by another single-celled terror that thrives in warm freshwater: the so-called “brain-eating” amoeba, Naegleria fowleri. The amoeba caused 35 reported infections in the United States from 2005 to 2014. If N. fowleri enters a person’s nose, it can travel to the brain, where swelling triggered by the immune system kills most victims (SN: 8/22/15, p. 14).
In many realms of science today, “statistical wisdom” seems to be in short supply. Misuse of statistics in scientific research has contributed substantially to the widespread “reproducibility crisis” afflicting many fields (SN: 4/2/16, p. 8; SN: 1/24/15, p. 20). Recently the American Statistical Association produced a list of principles warning against multiple misbeliefs about drawing conclusions from statistical tests. Statistician Stephen Stigler has now issued a reminder that there is some wisdom in the science of statistics. He identifes seven “pillars” that collectively provide a foundation for understanding the scope and depth of statistical reasoning. Stigler’s pillars include methods for measuring or representing aggregation (measures, such as averages, that represent a collection of data); information (quantifying it and assessing how it changes); likelihood (coping with probabilities); intercomparison (involving measures of variation within datasets); regression (analyzing data to draw inferences); design (of experiments, emphasizing randomization); and residual (identifying the unexplained “leftovers” and comparing scientific models).
His approach is to identify the historical origins of these seven key pillars, providing some idea of what they are and how they can assist in making sense of numerical data. His explanations are engaging but not thorough (it’s not a textbook), and while mostly accessible, his writing often assumes a nontrivial level of mathematical knowledge. You’ll have to cope with expressions such as L(Θ)=L(Θ)|Χ and Cov(L,W)=E{Cov(L,W|S)}+Cov(E{L|S}, E{W|S}) every now and then.
While Stigler defends statistics from some of the criticisms against it — noting, for instance, that specific misuses should not be grounds for condemning the generic enterprise — he acknowledges that some issues are still a source of concern, especially in the new era of “big data” (SN: 2/7/15, p. 22). Using common statistical tests when many comparisons are made at once, or applying tests at multiple stages of an experimental process, introduces problems that the seven pillars do not accommodate. Stigler notes that there is room, therefore, for an eighth pillar. “The pillar may well exist,” he writes, “but no overall structure has yet attracted the general assent needed for recognition.”
