Zhou Xun and Huo Siyan two nights ago attended a Shanghai event. Zhou Xun was working on FLYING SWORD OF DRAGON GATE (LUNG MOON FEI GAP). In the cold winter she had to work on martial art action scenes in the desert, which was quiet a tough. She said that she had to ask Jet Li (Lee Nin Kit) for advice on how to make cool fight scenes. She said, "I realize that being an action actor truly wasn't easy because action has to be smooth. During the fight I couldn't have any expression, which was very hard. I have great respect for action actors. If I have a chance I would ask him how to make marital art expression in order to look cool."
