The Song came to power in the tenth century and they would remain in power until the thirteenth. One of the things that distinguished the Song rulers is that they embraced Confucianism. The Great Confucian Scholar of this period was Zhu Xi. He says that the most important thing an individual can do in life is to attempt to live a good life. The Song dynasty relies very heavy on the scholar-gentry. Historically, the scholar-gentry is very much steeped in Confucianism. The government relies heavily on the civil service. That administration tends not to prefer the military. China is vulnerable to invasion and conquest.
