Referring to the aesthetic standard of "three courts and five eyes+four highs and three lows", we should create a sense of maternal core and make comprehensive adjustments according to three principles:

First up and then down-first u and then v, first fix the hairline of forehead and temple, and then raise the lower court to increase support;

First outside and then inside-first make the outer contour to achieve smooth lines and firm skin, and then make the inner contour to increase the three-dimensional fullness and smoothness of muscles;

Deep layer first, then shallow layer-first, make deep bone filling to increase support, then make shallow brick sticking and splicing to improve facial smoothness and smoothness. Shape the combination of beauty of bone and beauty of skin.
