The method of calculating the level of parents in China is based on the generation between blood relatives, with one generation as the generation, such as two generations with parents and three generations with grandchildren; When calculating collateral blood relatives, it is determined according to the homologous relationship between them, just as cousins and grandparents are collateral blood relatives within three generations, and cousins and grandparents are collateral blood relatives within three generations.

In China, collateral blood relatives are forbidden to get married within three generations. To calculate the parent-child relationship between two people, we must first find out the homologous lineal blood relatives of both sides, and then choose the algebraic maximum and minimum of both sides and this blood relatives. For example, to calculate the generation between one's body and cousins, first find out that the homologous lineal blood relatives of both sides are grandparents, one's body is three generations from grandparents, and one's cousins are three generations from grandparents. If both sides are within three generations, then it is concluded that cousins are collateral blood relatives within three generations.
