Gong Xue, Guangfu —— Teaching situation in Song Dynasty: Chen Denggui, head of the expert group of the Fourth Cultural Relics Investigation Institute of Guangzhou, believes that Gong Xue, Guangfu, was the highest school in Guangzhou in Song Dynasty, equivalent to today's middle school. Moreover, there was an imperial examination system at that time, so entering the official school had to go through a naive examination, that is, you had to be a scholar to study here, and the teaching content was Confucianism.

Recovering Gong Xue —— Teaching situation in Yuan Dynasty: Because Yuan Chengzong raised Confucius, the founder of Confucianism, to an unprecedented height —— Confucius was named "Dacheng Saint and King", Gong Xue at that time was called temple science. Some experts have studied that the teaching methods, time and people who come to be taught in temples are completely different from those in academies. At this time, Fanshan Academy in Song Dynasty seems to be a "church" dedicated to promoting Confucian morality and ethics, while the study of temples belongs to social education. Through this form of temple learning, the fashion of respecting Confucius and Confucianism spread throughout the people and penetrated into all walks of life.

Recovering Gong Xue —— Teaching in Ming Dynasty: In the early Ming Dynasty, Temple Science was renamed Fu Xue. Gong Xue's function is different from that of temple studies in Yuan Dynasty. It is a place for new scholars to continue their studies after entering the school. Strict discipline, they should regularly participate in the monthly exam hosted by instructors, the annual exam hosted by academic officials (promotion exam) and scientific research (pre-exam before the township entrance exam). At first, there were 40 students, 1 tutor (called professor) and 4 tutors.

Guangfu Gong Xue-Teaching situation in Qing Dynasty: Inheriting the system of Qing Dynasty and enlightening the people, Fu Xue's function was basically the same as that of Ming Dynasty. On the first and fifteenth day of each month, all newly admitted government students are led by government officials to worship in Dacheng Hall, and then pay homage in Minglun Hall, and then formally become students, which is also called entering Pan Pan and enrolling. During the Jiaqing period, the discipline was gradually relaxed, and the official school was no longer the main place to study, but it still had certain symbolic significance. As the first pass of the imperial examination, being eligible to participate in the pilgrimage entrance ceremony here marks that scholars can start on the road of study and examination.
