I agree with me. Since the government cannot fundamentally solve the haze, don't use schools as a solution, please give all schools including kindergarten use winter vacation time to install PM2.5 removal of the ventilation system and replace the filter regularly. It is understood that the PM2.5 can be controlled within the National Museum to 5 micrograms. The importance of cultural relics, on behalf of the past, the child is more important, because it is the future of the motherland. No action has no change. For the sake of the health of the children and for the future of the motherland, I urge the government to act as soon as possible. For children, please hand forward!!!
