Bernice Liu Bik Yi yesterday brought her dog to attend a Christmas charity event for raise fund for Doctor Pet. Bik Yi expressed that lately she has been working in the Mainland on a series and the film IP MAN CHIN JUEN (IP MAN PREQUEL), in which she worked with Crystal Huang Yi and Du Yuhang for the first time. Did she have to learn Wing Tsun? She said, "I don't need to. I wield weapons. During the shoot Yuen Biao also taught me a lot." Bik Yi said that she did not know any kung fu so she had to be more careful with weapons. She suffered bruises on her arms and legs. Luckily she had a dance background so the learning was simpler.
