Ronald Cheeng Chung Kei worked on his new film KEI YUEN FUI GOO LEUNG (STRANGE ENCOUNTER CINDERELLA) with Annie Liu (Lau Sum Yau) on the streets of Central.
According to an article in hktopten, it was a chilly day, and Sum Yau only wore a flimsy jacket and shorts. She was so cold that she often sniffled and shivered.
When she was not in a scene she immediately put on her down jacket to keep warm.
In one scene, Ronald was seen running into Sum Yau. He attentively changed her shoes for her, and it was then that they embraced and kissed.
Ronald and Sum Yau kissed for ten seconds each time. They did three takes before the director was pleased.
After 30 seconds of kissing, Sum Yau reportedly felt drained, and she immediately had to apply lip moisturizer to protect her lips.
