The formal education system was founded by Zhu and developed in the Song Dynasty. At that time, wealthy businessmen and scholars raised their own funds, built study rooms in secluded places in the mountains, or bought school fields to collect rent to supplement their funds. The rise of academies in Song Dynasty began when Fan Zhongyan was in charge of Fu Xue, Du Nan, and flourished in the Northern Song Dynasty, especially after the Qingli New Deal. At this time, there are four colleges. The Southern Song Dynasty was even more prosperous, and it was hosted by Confucianism and became a Neo-Confucianism Academy.
