To judge a person's quality, we should judge him by his actions, words and deeds. If you are hungry, he will give you a piece of bread, and he will be a good man ... Lu Yu is unfair, draw out a sword to help! He is a good man ... he doesn't do things that embarrass everyone, and he dares to help others when they are in trouble! He's a good man! On the contrary, he harms the interests of others, violates the law and discipline, and does things that harm everyone's interests ... he is a bad guy! I despise such people!
