Why didn't Master Longhu have Jet Li?

I can't make this play because of my injury. According to the behind-the-scenes information of "Dragon and Tiger Heroes", the bamboo ladder fighting in the warehouse was praised, and the martial arts movements in the picture were smooth and hearty. However, in the actual shooting, Jet Li was unable to shoot the play because of injury, and the main movements were done by martial artists for him, so the Dragon and Tiger Heroes did not have Jet Li.
