What is the lecture hall of Peking University Sinology?

Is it from the history department of Peking University? I am very responsible to tell you that the lecture hall of Chinese studies in the history department is deceptive. It is operated by a company called Huaxia Confucian Merchants. A friend of mine learned it in it, and it was ok for the first time. He was invited by a teacher in the philosophy department of Peking University. Later, the teacher of the philosophy department will give a lecture in the Chinese studies class of the philosophy department. They invited a teacher at random, and my friend went on strike on the spot. This is also deceptive. We're still in litigation. The nickname of Confucian businessmen in China is China Traditional Culture Development Training Office. The general manager is Yao Yongkui. They are profiteers who cheat in Peking University coats. Their company is on the fourth and third floors of the West Building of Peking University Resources. Many rooms are full of so-called "teachers of Peking University". My friend took me to see them, and I was shocked. The history department also turned a blind eye and even supported them.
