Legal basis: Article 12 1 of the Civil Code of People's Republic of China (PRC). Inheritance begins at the death of the deceased. If several people related by blood died in the same event, and the time of death is difficult to determine, it is presumed that the person without other heirs died first. There are other heirs. If there are different generations, the elders are presumed to die first. The presumption of the same generation died at the same time, and there was no inheritance.
