Hi, Wan Mei of Crystallized found a candid photo taken by a blogger (a "Mrs. Lucia") of Crystal Liu Yifei and her mom. "Mrs. Lucia" is of the opinion that Crystal Liu Yi Fei "is going to Hong Kong for work-related activities."
Excerpt of Wan Mei's comments:
This photo is made by a blogger for the same flight, "Mrs. Lucia". She took the photo as Yifei is waiting directly in front of her on the immigration (passport) control line.
