Sharon Yeung is not the producer of the film, but the executive producer (also presenter)
Ken Yip Wing Kin is not executive director of the film, but the action director (Douglas Kung is the martial arts director, too)
For the moment I added the correct credits, and if nobody stops me in 15 days, I will remove the wrong ones.
And if nobody stops me in 15 days I will change the main name of Hung Cheung Tak by the most common "Douglas Kung".
