Therefore, the property of this house should be a half-brother.
I agree that people who enjoy this third-floor house should subsidize those who don't. The exact amount can be negotiated.
As for buying a house again, his parents will pay as much as they can. After all, it is to buy a house for my son, not an outsider. And it's not easy to live hard after 80, so I don't have that much money to buy it. Parents should help.
Then the rest, if they can't help, earn money to support their small families.
That's what I thought. Is it more reasonable?
