FYI, I also introduced to you another similar analysis of Mr. Cai in my previous posting at https://blog.udn.com/kkuo0810/171898895 

PS: I once visited the memorial hall of Cai Yuanpei in the Jinan District of Shanghai many years ago. I remember the custodian of the hall asking me if I was from Taiwan.
