If we stay in the chimney of society for a long time, we will become polluted unconsciously. This world is like a big mirror. The sinister, ferocious, and cunning human heart has covered it with a thick layer of dust, so each of us must do our part to wipe it. As long as we polish the part that belongs to us, we will find ourselves smiling in the mirror. We must be kind people and make everyone in the world do good, so that we can truly save the world. Like a sunflower, it always grows towards the sunshine and towards hope.
