Yan Feifan had originally scheduled the plastic surgery for Fang Yin, whose jaw had an ape-like protrusion, to begin at seven in the evening.
However, since Fang Yin had arrived at the plastic surgery center early that morning, and Yan Feifan had to get to Mr. Wang's house that night, he moved her surgery up to three in the afternoon.
The key and most difficult part of Fang Yin's surgery was setting her upper and lower jawbones back by an appropriate degree.
The degree of this setback needed to account for facial aesthetics while also maintaining the harmonious alignment of the upper and lower jaw.
In simpler terms, her bite.
If the bite alignment was poor, it would, over time, affect Fang Yin's digestion and nutrient absorption, which in turn would impact her overall health.
