What an interesting research
wou! It seems there are some differences in the lineages of KYCH Northern Shaolin, from GM Wong's information compared with Chan Kowk Wai's and Kwong Wing Lam's.
It would be nice to make more research about the subject. My students went to China (GwangZhow) two times to train under Lai Kan Ching, who was KYCH direct students, I will see if they found some good info about this.
As far as I know there are still alive TWO Ku yu Cheung students.
It is sometimes said that Yim Sheung Mo was the highest student of him ¿can anyone corroborate this info?
I will try to contact the NSL family in QwangZhow to ask for a lineage three.
Kind regards
