No casualties have been reported so far, while China's Ministry of Emergency Management has dispatched additional rescue personnel and heavy engineering equipment to Zhoukou to support ongoing emergency response work.
A total of 781 local residents have been evacuated due to a levee breach on the eastern bank of the Jialu River in Zhoukou at around 11 pm on Thursday, due to pressure from upstream inflows on the Jialu River and backwater from the Shaying River, the breach is about 30 meters wide, according to the Xinhua News Agency on Friday. 
The Ministry of Emergency Management has dispatched 200 personnel from China Anneng Group, along with 110 sets of large engineering and rescue equipment, to Zhoukou, after the levee breach on the Jialu River, the ministry said on Friday.
The rescue force, equipped with powered pontoon boats, amphibious excavators, loaders and other heavy engineering machinery, arrived at the scene by 10 am on Friday and immediately began emergency response and rescue operations.
CCTV News reported that the breach flooded a hospital compound and a driving school in Zhoukou, with floodwaters reaching up to 1.5 meters deep.
After the breach occurred, Zhoukou's fire department mobilized 290 personnel from seven nearby brigades to the scene, deploying loaders, inflatable boats, motorboats and other rescue equipment to search for and evacuate stranded people area by area.
According to Henan Daily, another levee breach occurred along the left bank of the Beiru River in Jiaxian county, Pingdingshan, earlier at around 7 pm on Wednesday. The breach, measuring about 47.5 meters wide, prompted local authorities to evacuate 2,182 residents from six villages in two rounds. No casualties were reported, and all evacuees were properly accommodated.
According to an official notice from Yanling county in Xuchang, another levee breach occurred along the Qingyi River near Cangtou village on Thursday, as continuous heavy rainfall kept the river at high levels. Local authorities immediately launched an emergency response and organized evacuations and other risk-prevention measures. No casualties have been reported.

。根据研究，在新冠疫情期间，数百万人因各种原因离开了劳动力市场，包括退休、缺乏儿童保育和对新冠疫情的恐惧等。8月份劳动力总规模达到1.647亿人，首次超过2020年2月疫情前水平。但该研究作者、斯坦福经济学家戈皮·沙·戈达以及麻省理工学院经济学家埃文·J·索尔塔斯表示，如果没有疫情影响，劳动力总人数预计将增加50万人。若美国持续保持当下新冠感染水平，预计将损失更多劳动力。部分经济学家认为，美国劳动力的缓慢复苏以及对工人的高需求是美国经济面临的主要挑战之一，这限制了雇主提供商品和服务的能力，并加剧了价格压力。专家称，解决这种不平衡对于降低高通胀至关重要。（总台记者 张颖哲）返回搜狐，查看更多责任编辑：
