Abstract:The adopting children phenomenon originated from the thought of chinese traditional clan, in the Tang and the Five Dynasties, people who had ulterior motives using this special relationship to win and expand forces, then formed a hitherto unknown general mood that was adopt children. This relation was mostly based on benefits, so it could cause fighting easily because of power and benefits. But there were also people who would like to sacrifice for their adoptive father .This complex relationship not only had an effect on their success or failure, but also had a certain influence on the whole society, on the one hand, it expedited the process of dynasty changing, on the other hand, it hindered the pace of the new dynasty to complete the unification of the whole country.
