The set of Grand Master Yip Man on a Shanghai soundstage is the film of Butterfly Lovers/Butterfly Swords, with starring Wu Zun and Charlene Choi as the re-incarnations of the star-cross lovers, with choreography by Ching Siu Tung, is also going on nearby. They were filming a scene whereby Yip Man (Donnie Yen) goes shopping with his wife Zhang Yong Cheng (Lynn Hung) and son Yip Chun (Li Ze) in the bustling streets of Foshan. However, owing to unexpected drizzle, filming was affected. At one end of a street is the congregation of all kind of martial arts schools. The set will be altered at a later stage to give a worn-down, grim and dismal look following Japanese invasion and occupation.
