Crystal Liu tweeted on weibo on Nov. 14, "Heard that Bai Lao Er wrapped today, feels like the second picture, so looking forward to practice all the way till next year. Fight, fight!" I didn't know what she was talking about then but her attention-grabbing hair got me googling.
Apparently, she just wrapped a movie called Yi Dai Yao Jing where she plays an 87-year-old fox demon named Bai Xuan Chu who falls in love with a modern day human played by Feng Shao Feng. The plot resembles My Girlfriend is a Gumiho to a tee, which is my favorite k-drama ever so I'm definitely onboard with this one.
