In order to conform to the role in the play, Yang went crazy to lose weight before appearing in the play, and successfully lost 20 pounds in January, transforming himself into a "skinny beauty" required in the play. Jiang, who plays in the new version of Daiyu, has a "baby face" common to adolescent girls and looks young and sweet. However, the "Hu Zao" she played in Xikou Love Song is a strong and determined northwest woman who dares to say and do. With such a role and such a background, Yang felt that his "baby face" was a bit inconsistent, so he had the idea of losing weight for the role.

In order to achieve the effect as soon as possible, Yang adopted the method of diet and exercise for a month. Not eating after noon, resisting sweets and jogging regularly are all necessary "exercises" for her every day. Sure enough, many things happen. Now, the doodle "babyfat" on her face is gone, and her legs are beautifully decorated. Even when the deputy director who chose her met her, she couldn't help praising "I haven't seen Sanqiu for a day".
