Abstract: The literature materials from “May 7th Cadre School” (“五七干校”, in 1970’s) is a field needs academic to collect and reorganise, for it is in the severe haemorrhaging. On the basis of limited stuffs, this paper compiles a chronology. But owing to the lack of abundant “background materials” to support the argument, there are some points are not speak in detail or just has single evidence. That is the reason why I intend to write the paper. According to the chronology, the paper gives a full account of extant materials and other scattered stuffs which urgently need to edit. Furthermore, I would like to enumerate the main idea of related doubtful points and emending examples. Of course, there are still some questionable points in the text remain to be further enriched.
