SINGER Li Yuchun, 27, can’t get enough of martial arts (武术). Having made her debut in Bodyguards and Assassins (《十月围城》), she now portrays a swordswoman in Hong Kong director Tsui Hark’s Flying Swords of Dragon Gate (《龙门飞甲》). At one point in the movie, Li has to swing a big knife. She said the hardest part was not actually how heavy the knife was, but managing to swing it freely while still focusing on her lines and facial expressions.
