How can I get along with my powerful parents-in-law who look down on me without being bullied?

Depends on what kind of personality you are. Different people will have different ways to deal with the same problem. What others can do may not be suitable for you.

The most important thing is self-confidence and hard work. They can look down on you, but you have to look up to yourself and do what you should do, so that you can be reasonable and disciplined. If you have the ability to impress them, there will be no problem. If you can't, learn to protect yourself. Don't wait for others to guide you to do this or that. Over time, it will become a habit. Take the initiative to do something good for them As the saying goes, if you don't smile and slap people, even small things will warm your heart. But you must be natural and confident, don't pander to anyone in a low voice, and do your best. On this basis, don't be too sensitive, occasionally encounter some misunderstandings or setbacks, don't care too much, and try to avoid direct conflict with them. When you encounter a dispute that is difficult to mediate, you'd better talk to your husband, not complain, but discuss the solution together and let him know that you are doing this for the good of your family. In fact, the core of maintaining the relationship between mother-in-law and daughter-in-law is the husband. As long as you love each other, even if you are wronged by your in-laws, he will understand you and repay you, and he will not suffer. Therefore, it is more important to find ways to maintain the relationship between husband and wife.
