Well I belive that Jet’s favorite form is Tong Bei Kuen.
He has bee doing this form for a long time!!!
Jet Li Documentary with him in the blue robe uniform
Once Upon A Time in China part 3.
When the girl wants to tryout that little camera she made. Jet went up there and did a few moves from the form.
Jay Leno show for Lethal Weapon.
He does a few moves and then some tai chi.
Romeo Must Die
On the part where Jet fights with Russel wong on the pier. Before Jet goes out there , the film shows Wong doing a few moves from TONG BEI KUEN! And I suspect Jet showed him those moves on the set! I learned this form too but it looks nothing like Jet’s. haha.
I remember from an interview in an old magazine that he likes to do Tong Bei Quan, Fan Zi Quan and Pigua also… as those seem to be the main things he demonstrates. I think also now he does a lot of Taijiquan and other ‘internals’
