Others have

it that Wing Chun, having fallen in love with Leung Bok Cho, intentionally allowed him to defeat her. When she later revealed this to him, he laughed at the notion, but Wing Chun invited him to fight again and beat him convincingly, demonstrating that she spoke the truth. She then taught him the Wing Chun system.
Jee Sin is also credited with teaching Kung Fu to Hung Hay Gung, from whom descends Hung Gar style ("Hung Family Boxing").
Some say that Jee Sin was related to Wong Wa Bo and the Dragon pole was passed to him as a normal family heritage, rather than being initiated via the encounter on the Red Junk. Another version says that he had joined the Red Junk earlier, disguised as a cook.
One account has it that the modern dummy was invented on the Red Junk with the mast forming the body of the dummy, with the arms and leg detachable so they could be hidden from prying Manchu eyes while the Junk was in port. This story also has it that the dragon pole's original form was that of the oars or poles used to guide the Junk.
