if it doesnt matter then thats great. you should have no problem discussing what is reality without getting upset. for the record im not trying to state who is better, im just stating facts as i was told. those facts coincide with some evidence. you can choose to believe or not.
i did not say sum nung taught yip man. yuen kay san taught yip man sticky hands for a few months briefly. yip man did not know sticky hands before this. all he really knew was how to use the chung choi (chain punch). this is probably why yip man's understanding of sticky hands is superficial, just skin deep at best. this is probably why there is so much confusion as to what sticky hands is. some say its just a drill just an excercise most likely because they cannot make it work in a real situation.
recently i read about yuen kay san in wingchunpedia (
http://www.wingchunpedia.org/pmwiki/...CP.YuenKayShan)
in the last paragraph it talks about yuen kay san teaching yip man briefly when yip's house was burned down and yips grandfather being an opium boat captain. these details i had not heard of. i had only been told about yuen teaching yip a little sticky hands.
