The Hinayana Abhidharma became popular in china earlier than the Mahayana Prajna, and exerted more influence. It had the same opinion as the Taoist "Spirit-being" School in advocating the no-change of race and the no-change of people's nature. It is the philosophical pillar of Buddhist theory that "The form will decay but the spirit will never extinguish". It also provided a systematic and theoretical explanation on the then clanish rules and Confucianist filial piety. Therefore, it became the theory with the most Chinese Buddhist flavor.
