On February 15th, elementary school students will start school. This year, the teachers have set up another one for the elementary school students

"Defending the blue sky, start from me" as the theme of the essay, from so many copies I printed, I clearly saw this sentence: "The teacher said that the Chinese New Year is not allowed to set off guns, I am not happy, I listen to the teacher's words, do not fire guns." "Damn, haven't you killed the children's nature again!

It's just a matter of forcible control during school, and now they don't even let go of the holidays, do children still have childhood?

It's PM2.5 again, and the children are required to take care of those car exhaust emissions and factory exhaust emissions!

A while ago, it was said that housewives would produce PM2.5 when cooking, but now they think that children will produce PM2.5 when they set off firecrackers, and there is no humanity!

If you don't die, you won't die!
