Last month, some residents of Zhuozhou, a city in northern China, protested after much of the area was flooded once officials opened flood gates and spillways in flood control zones. The action was apparently meant to prevent the waters from overwhelming bigger urban areas, including Xiong’an, a new city championed by China’s leader, Xi Jinping. On Thursday, Mr. Xi visited Shangzhi, a city in China’s northeast that was also struck by the floods last month.
Classes were suspended in Hong Kong, Shenzhen and other parts of southern China on Friday. But across the region, some people returned to work, despite transit disruptions.
