The whole town people make nucleic acid         

                 The most important thing for national nucleic acid is to do a good job in epidemic prevention and cooperate with the police and volunteers,

The children are also obediently cooperating

Everyone has worked hard, I wish our country peace and prosperity

Look at the orderly line up
