I've mentioned Master Chen to you many times in my previous writings.  Attached below is a rather detailed account about his family background, his ways up to a peerless guru in Chinese history and classics, and his being a star-crossed victim throughout the tulumtous years, especially during Cultural Revolution.  However, I must point out here that according to the report, Chen's blind eyes and fractured legs that happened to him had been prior to that misfortuante period, but the author insinuated later in the same report that Chen's physical pains had something to do with the Revolution.  Obviously it is an Irish bull itself.  Anyway, please read the report at:   http://www.toutiao.com/a6474441533381673485/

P.S.  There's another memorial article wrtten by Mr. Yu Dawei (俞大維), Chen's cousin and best friend, at http://www.toutiao.com/a6474199916675219725/
