Two patterns of thinking existed from Three-Kingdoms to South-North Dynasties,one of which was based on traditional Chinese thought accompanied by the impact of Taoism, Buddhism and then the so-called "three religions competition" took place in the Three Kingdoms, Jin and Southern Dynasties, and the other is based on minority people's traditions accompanied by the impact of Chinese thought and Buddhism and then the two events called "suppression of Buddhism" took place. In the two different patterns, the trend was also different. The former was Confucianism continued decline and the Taoism and Buddhism in particular continued increasing, as a result, politics unstable and the state weak; in contrast the latter was minority people's traditions continued decline and the Confucianism continued increasing the state become stronger and ultimately unified China.
