I think this sentence also applies to love. When two people are in love, don't try to change your other half. This may be the most difficult but important principle in a stable relationship. You need to accept your partner, otherwise, you will certainly frustrate yourself and alienate your lover. If you can't accept your partner's true colors, you need to set boundaries to avoid harm. You need to understand that men and women are different, or you need to understand that different men and women are different, and don't unfairly let your partner reach the standard of ideal relationship.
Similarly, please don't control your partner too much. Violence is not the way to control your partner. If you can't handle compromise, then leave this relationship and don't try to control or change your partner, which will make him very disgusted.
In addition, to support your partner's interests, you don't have to share every hobby of your partner, but when your partner talks about their interests, you should listen to them and give them free time and space to pursue their interests.
Finally, don't underestimate your partner's emotions. Although not every emotion is desirable (such as anger, resentment, depression), it is normal. If your partner is angry about something, don't criticize them. Anger can be destructive or constructive. Criticism can make your partner feel guilty, defensive and withdrawn.
In a word, this sentence contains a lot of love philosophy, which deserves our deep thought.
