Some role names:

Wong Yu - He Jiayu
Yuen Tak - Debao
Chiang Kam - Wu Dezhi
Yeung Pan Pan - Chen Xiaowei
Kwan Hoi San - Master Wu Changjiu
Yen Shi Kwan - Zhang Liyi
Hwang Jang Lee - Luo Yihu

I would also remove the "Historical Drama" tag and replace it with "Comedy", despite the film being seriously unfunny.
