What should I do if my only daughter wants to emigrate and can't let go of her parents?

Choose between parents and going abroad. If you choose to emigrate: Maybe you are used to living abroad and have many foreign friends. The living environment is superior, the treatment is better and you get material satisfaction. If you choose your parents: you will give up everything before, and then be filial to your parents and get psychological comfort. Immigrants bring material wealth and superiority in future children's education, while not immigrating to stay with parents brings filial piety. The two can not be distinguished by good or bad, and there is no difference between quantitative change and qualitative change. No matter how many material advantages immigrants bring, they cannot be filial to their parents. No matter how much filial piety you have done to your parents, you can't make up for the material lack. Everything depends on the weight of both in your heart.
