What should I do if I can't find an heir to the inheritance dispute?

If we can't find all the legal heirs, then after a period of time, the inheritance will legally belong to the state and be used for public welfare undertakings. If only some people can't find it, they will keep part of the inheritance according to law. If the successor in the first order cannot be found, it will be inherited by the successor in the second order.
