I have seen a family with a grave behind it and a grave beside it. The conditions at home are good, the owner is the boss, and it has been smooth and profitable.
The descendants of the people on the side grave are also good, most of the four or five brothers are good, and it is not bad to be a small official or boss.
Of course, some families with graves next to them are very bad. There is also the grave of the house next to it, and there are also bad situations.
