Filming often doesn't see everyone wrapping at the same time. Some actors, due to their contracts, may not even have their roles secured when shooting begins, and they might leave once they've completed their parts, even if the whole film isn't done yet.
In the entire film, Xia Siyu and Bo Yan had the most parts, and they were the artists who stayed the longest in the production crew. But no matter how long one stayed, there were always different scenes to shoot.
"Spring Light" was about to wrap up, with Xia Siyu finishing her scenes first. She had the movie "Youth 2" lined up, as well as a variety show with her agent Qin Baizhou, both of which she had already signed contracts for and couldn't be delayed.
Besides that, she had several other variety shows, but they were mostly studio shoots, so she could do them once she was back in Yancheng.
