Many people take "if you can't change the world, change yourself" as their motto, but some people, sometimes, if you really can't change yourself, try to change the world, maybe not much, but "it's a good thing that the world is better because of your efforts", which is what my respected Luo Yonghao said! I am also a border resident. This sentence is an encouragement to you. I wish your mother a speedy recovery!
