Who is Chang Yuan? Who's Ke Sun?

The two should be colleagues or neighbors of Haizi when he was teaching at the University of Political Science and Law.

In those days, I participated in discussing topics such as Qigong religious philosophy with Haizi.

Haizi said in his suicide note that being persecuted by two people may have been written when he was mentally abnormal.

But before I died, I wrote: My death has nothing to do with anyone.

After Haizi's death, the public security organs also investigated the relevant personnel in the suicide note, but did not pursue any legal responsibility.

Chang Yuan wrote an open letter about him and Haizi. We can look for it.

I ignore these things because they should be Haizi's subjective imagination after practicing Qigong, and have nothing to do with these people. If you write a big book, it will have unnecessary influence on these people.
