You are still a student -- a flower cultivated in a greenhouse! I forgot, you are a history student - a university student specializing in the Cultural Revolution in China! ... More fatally: I forgot that education in China serves politics, early childhood English education. Therefore, we should thank the Internet -- for getting to know you and your teacher -- Li Changwei et al., traditional Chinese learning textbooks, and learning about Mao Yu-shi, Yu Dan, Sun Liping, Zhang Wuchang, etc. Thus allowing us to have more, more comprehensive understanding and recognition of our country and society, one-on-one personalized tutoring in Tianjin. There are many ways to understand history -- comparative method, vertical and horizontal method, personal accounts from those who experienced it, documentary evidence, natural science records, etc. The reason I recommended you read those articles is for discussion, hoping for a fair judgment on history, and ultimately restoring the truth to the people. Now, within just one inch of his brain, I recommend my not-so-good article -- "Viewing the Evolution of Chinese Thought Through the Lens of Land Leasing as Described in Political Economics," allowing you to see the true face of Chinese education from a different perspective.
