How to persuade parents not to interfere in their own decisions?

Rights and obligations are matched. If your life depends on them now, they may feel that since they have done their duty to take care of you, they should exercise their responsibility to manage you. If you don't rely on them, just tell them that you are an adult, take charge of your own affairs and bear all the consequences. The losses caused by their own decision-making mistakes will not affect them. If they don't respect your decision, you can ignore their suggestions. If you can't or won't give up their help or charity, then shut up and be good. Eating people is the shortest.
