Regarding men marrying, do parents have the obligation to build a house or buy a house for their son? Is it the duty of parents?

Parents have no obligation to build a house for their son. If you can't marry a daughter-in-law, it's useless to blame yourself. People can marry a daughter-in-law with two hands. Are you short of arms and legs? Why not? Parents have worked hard to create wealth and want to leave it to their sons, so that their sons can struggle less for a few years. The intention was good, but his son took it as an obligation and made a joke. China has a lot of shit and scum. If parents have the obligation to help their son buy a house, it is easy to lead to the dominant thinking not by themselves, but by parents. This kind of social atmosphere is not good, has a bad influence and has many side effects.
