Sinology is the traditional culture and scholarship of China compared with the western learning introduced to China in modern times, and there was no such title in ancient times. The preface was originally a place for teaching and shooting, and later developed into a place for slave owners and nobles to discuss politics, sacrifice, pension and other public activities, as well as a place for slave owners and nobles to educate their children. Build it into a school to teach it. "Mencius Teng Wengong": If you are embarrassed, you will raise it; Learn and teach; Order, shoot also. Thank you~
