Why don't some parents in Zhejiang like foreign daughters-in-law? Does it matter where people are wives?

This is the case here in Zhejiang. Not only do you dislike foreign wives, but also foreign son-in-law doesn't like them very much. There are actually many reasons. Parents have traditional ideas, and some things are deeply rooted and will be discussed among neighbors. There are many non-locals working in Zhejiang that are uncivilized and unsanitary. Parents take it for granted that mainlanders are like this. I think you should do your best as long as you have a clear conscience. If you can't change their mind, at least you respect others and yourself. Believe in yourself, if the good is invisible to others, it is the loss of others. Of course, if you want to change others, you should also change yourself. This is the way we get along. Only when someone takes the initiative in the world can people get familiar with each other and understand each other.
