How to persuade father to drink less?

Whether you can really persuade your father to drink is actually very difficult. It's impossible not to drink. After decades of accumulation, people have feelings, good and bad. If you can really quit, it is really a terrible person. Even if such a "terrible" person gives up drinking, there will be other things that make people around him "uncomfortable". There is no end to persuasion, and the result of persuasion is actually the same as that of my father. For example: Are you easily persuaded by others? If it is easy to be persuaded by others, then his father should be easily persuaded by himself. Everyone has nature, and nature comes from parents. It's hard to change Look at nature and read books. Sometimes what you don't want your parents to do, in fact, you will do it eventually. It was just a different place at that time.
