You say you were walking on campus when a black bag was suddenly thrown over your head and you were stuffed into a car before being arrested?

Yes, this is how it happened. I never returned to classes and I did not graduate. My classmates were told that I had a mental breakdown. After my release, I did what I was told and laid low at home (book, p. 255, pp. 258-259). I originally had been planning to go to graduate school to study comparative literature in Nanjing, but that could not happen due to the circumstances.
