The comparison of Zhang Bichen's before and after plastic surgery photos is a comparison of Zhang Bichen's appearance before and after picked up by netizens. Of course, there are some differences between the previous photos and the current ones, but there are no major changes. Some netizens also said that Zhang Bichen's chin has become sharper and the corners of her eyes are also obvious. The bridge of her nose has also become higher, but these changes cannot be confirmed to be plastic surgery, and it cannot be ruled out that they are caused by makeup effects. She herself has not responded to the rumors of plastic surgery.
