HARBIN, March 24 (Xinhua) -- After climbing an iron ladder and mounting a 10-meter-high drilling platform, Ge Yifan, a driller in the Daqing Oilfield, keeps a close eye on the control room screen and uses a microphone to instruct his workmates cleaning mud off the platform.
He cited a paper by British and German scientists published this month suggesting that the SARS-CoV-2 variant circulating in the United States was a more "primitive" version of the one in China, and might have appeared there first.
Chen also stressed the importance of emphasizing the huge demand for digital transformation and improving new digital infrastructure to facilitate economic and social upgrade of the country.
It also stressed stabilizing foreign trade and investment, assisting businesses, stabilizing employment, creating more jobs, helping college graduates and migrant workers find work, and solving difficulties for small household businesses.
Xi went to Niubeiliang National Nature Reserve in the county of Zhashui, Shangluo City, to inspect ecological preservation of the Qinling Mountains.
