How to translate 国子监大讲堂 into English According to wikipedia, Guozijian （国子监）“sometimes translated as the National School, National Academy, Imperial Academy, Imperial University, Imperial College, Imperial Central School, National University,[2] etc., was the national central institution of higher learning in Chinese dynasties after the Sui. It was the highest institution of learning in China's traditional educational system, with the function of administration of education.” “国子监大讲堂” is a lecture series (讲堂） about traditional Chinese Culture. Guozijian no longer exists now, but it is a symbol of Chinese traditional culture, thus the lecture series is named "国子监大讲堂”. I'm having trouble translating it into English. I'm considering the following translations: "Imperial College Lecture Series," "Lecture Series on Chinese Culture” or "Guozijian Lecture Series." Which one makes more sense? Or is there a better translation? THX!
