Because Zidan lost weight while filming Ip Man, she often ate nothing. In order to maintain his strength, he had to sit there and rest, not filming. Ip Man is a scholar, and you can't have too many muscles. In addition, when wearing clothes, Zidan's muscles are not so obvious. When shooting the Royal Guards, Zidan strengthened the muscles, so the muscles you saw are real. In fact, his muscles are not as exaggerated as those of the Royal Guards, but they are also true.
