Witnessing the great feats of Chinese people working together and rising to challenges, the children have followed the call of the Party and the government to support the anti-epidemic battle with their concrete actions, demonstrating the fine spirit of the country's children, Xi said.

He stressed that China's children today are not only undergoing and witnessing the realization of the country's first centenary goal, they are also a new force for achieving the second centenary goal and building China into a great modern socialist country.
