"Originally, I just wanted to replicate the role and return to the state I was in before, but after seven years, I realized there were many things that needed adjustment. The time is different, the sense of age is different, the experience is different, and my understanding is different. Compared to 13 years ago, when I look back to find the character again, I realize I understand him better now," says Yu, 43.

For Cheng, 47, who played the role of Yuchun for the first time 13 years ago, putting on that same outfit and styling her hair the same way is emotional.

"Looking in the mirror, I feel that neither time nor age are problems. I am the role again," she says.
