A | (ECNS) -- Shenzhou-21 astronauts Zhang Lu, Wu Fei and Zhang Hongzhang met the press at the China Astronaut Research and Training Center in Beijing Wednesday, their first public appearance since returning to Earth and completing post-flight quarantine and rehabilitation. Their 210-day mission set a new record for the longest single crew stay by Chinese astronauts. During the mission, the crew completed three spacewalks, installed space-debris protection devices and carried out experiments in fundamental physics under microgravity, materials science, life science, space medicine and space technology. The mission also saw several firsts in China’s crewed space program: a spacecraft return delayed after a space-debris strike, a crew switching spacecraft for the journey home, and an emergency spacecraft launch. Zhang Lu completed seven spacewalks across the Shenzhou-15 and Shenzhou-21 missions, setting a record for a Chinese astronaut. Wu Fei, who helped develop the Tianhe and Wentian modules before becoming an astronaut, said operating the equipment in orbit gave him a sense of familiarity. Zhang Hongzhang shared several scientific breakthroughs achieved during the mission, including China's first successful aeroponic cultivation of cherry tomatoes and wheat in orbit, the first closed-loop breeding of mice in space, and the validation of key technologies for efficient spectral and water-fertilizer utilization. An official from the China Astronaut Research and Training Center said the three astronauts are in good physical and mental condition, with their muscle strength, endurance and cardiorespiratory fitness largely restored to preflight levels. They have entered a recovery observation phase and will return to regular training and work following a final health assessment. (By Intern Yang Hongran, Zhang Dongfang) 。

B | 别让资金“过夜等待”，货币ETF赎回到账我们快人一步在投资的世界里，资金效率就是收益的一部分。对于熟悉场内货币ETF的投资者来说，这原本是打理闲置保证金、获取稳健收益的利器。但在赎回环节，很多投资者会忽略一个关键问题：赎回到底要等多久？行业普遍情况：T+2到账是常态根据市场主流规则，货币ETF若走“场内赎回”通道（即向基金公司直接赎回份额），资金通常要等到T+2日才能可用或可取。
