In March, children of all the primary and secondary schools in Lhasa are ushering in the spring semester of 2021. The quiet campuses have regained former vigor and vitality, and there are full of sounds of reading and crisp laughing.

At 8 o’clock on the morning on March 2, the entrance of Lhasa No. 1 Primary School was very lively. While being escorted by their parents, the children carried school bags and walked into school excitedly after undergoing epidemic prevention and control measures such as temperature checks and disinfection.
