By the time I arrived the Hong brothers had been expelled from the school (I believe that happened around 1963 or 1964). The only contact I had with Hong Yixiang was at a farewell dinner Mrs. Zhang arranged to see me off when I was preparing to leave the island. He was obviously pissed off at the favor shown to me by the Zhang family, but was basically told to shut up and behave by the others present who were friends of mine and the Zhang family: Zhong Fusheng, Liao Wuchang, Gao Daosheng, several of Master Zhang's first and second generation students, some Yi Guandao associates, as well as some native Taiwanese martial artists whose names you would not be familiar with. I believe the purpose of inviting Hong was to let him know in no uncertain terms that I was a part of the school under the Zhangs.
Confirm with Hong's family.
Hong's expell from Zhang's school is not true~
Check with Hong's students and Hong's sons.
Expelling from one's school is one serious claim~
Just to clarify this~ and return honor to the master.
Cheers,
