Hong Kong yesterday turned cold with only 13 degrees Celisus temperature. Nicholas Tse Ting Fung and Guey Lun-mei had to brave the chill at 11AM to work on the film THE STOOL PIGEON (SIN YUN) at the Wanchai Emperor jewelry store. In the film Ting Fung's costume was unique. With a shaved head he not only had scars on his face but also played an employee of rich kid Guey Mei-lun, holding bags and bags of Guey Lun-mei's shopping conquest. With the cold and their flimsy costumes, after every shot they immediately put on their heavy coat to keep warm.
