Extract: This is the root cause that drove me to study history. It is not about writing a few papers, doing some research, or following Yang Kuisong or Shen Zhihua in the hope that I could be another academic authority after they die or twenty years later. I first want to save my life. History study is secondary. In the case that I have already saved my life, I will yield a bit to my vanity and prove to everyone that the real history is actually not what the kind of thing that the academic workers imagine it to be. It is something more significant. There is something that is more consistent with its original meaning. It seems that all of these things have been forgotten by you, who even deem it trivial.
