Probably because of the needs of the role, characters experience, Chu Qiao, and so on (life, long-term running and enemies, fighting, etc. The image of the heroic positive energy female general must not be fat); There is another negative example. If the actor is a very fat person, he may not be suitable for this role. After all, the casting director of TV series should choose who plays Chu Qiao with more TV appeal and influence and TV ratings according to many reasons, such as character image, star schedule, market fan ratio, etc. Personally, I think so.
