before too much excitement, unfortunately I already knew some about Chen Duxiu. He is rightfully lauded for being very influential in overthrow of the Qing dynasty and in the early Republican era, as well as being a co-founder of the CPC. However he was later expelled (much history that I’m not qualified in summarizing, yet) and later found company with Trots (trotskyism was found to be the wrong line and almost nonexistent in prc today as far as I can tell)
