I think this may be because William Chan likes to manage his body, so he can keep fit at this age. In addition, William Chan, as a star, is also very able to control his diet, and he doesn't eat seaweed and exercise together at ordinary times, which is why he keeps such a good figure. Before Huang Xiaoming published his own weight-loss methods on the Internet, we can also find that Huang Xiaoming's weight-loss is also very extreme. In the process of losing weight, Huang Xiaoming won't eat any staple food, but some cucumbers or apples at most.
Most stars, who need to appear in front of the camera often, have strict management of their figure, and will control their diet through various exercises to keep a good figure. Bian Xiao himself thinks that judging from William Chan's face, he is not a muscular male star, but after taking off his clothes, he can obviously find that his figure is really good.
Stars often need to change according to different roles in the play, and William Chan, as an actor, also needs to lose weight or gain muscle according to his role. Muscle lines are very obvious, and it can also make the whole person look more secure, which is more suitable for some martial arts types. William Chan's acting skills are also very good, and I believe he can get more opportunities in the entertainment circle.
