丑鸭子

Meaning

"Face-changing Master" describes someone whose attitude and emotions have extreme swings. "Face-changing" is a Sichuan opera special skill where different masks appear with the performer's movements. Since masks symbolize personality, people whose emotions and attitudes change dramatically are called "face-changing masters." This change usually involves "Zhenxiang" and "face-slapping." Example: In "X-Change," Wang Jingze said with a fierce face "I won't eat your food even if I die" then transformed to happily saying "So good." Such people are called face-changing masters.
