First of all, from a legal point of view, if an old man has children, a large part of his inheritance must belong to his children, but this old man has no children, and at the same time, he has no so-called adopted son, so his inheritance can only be inherited by writing his own suicide note, but this does not exist, so in the end, this inheritance still belongs to the state from my point of view, but specifically, this needs legal trial, because it is likely to be part of him.
But from a legal point of view, it is true that the old man did not leave a suicide note, so no one can properly inherit his property. So from a legal point of view, it is very likely to belong to the state. Of course, such old people also need to be taken care of, and finally they didn't have children.
Living like this, even with a lot of property, is meaningless to him. No relatives around, he is old, no one to talk to, no one to accompany. This feeling is very uncomfortable, so I also hope that everyone can care about their old people and spend more time with their parents when they are old. This is what they need most.
