The facial makeup of Peking Opera changes with age, and Guan Gong's music style is no exception. There are different ways to hook Facebook, including prime of life, old age, before and after death (becoming a god). The most obvious is the color of the nasal fossa. In the prime of life, all the plays from "Three Knots in Taoyuan" to "General Feng Wu Hu" are black nose nests. In the old days, from "Flooded Seven Armies" to "Walking to Maicheng" were all gray-nosed nests, but after death, they became gods and had to be changed into black-nosed nests. This is directly related to the color of the mouth. After becoming a god, the three black lines on the forehead turn into gold, because gold shows the characteristics of becoming a god, forming thick eyebrows and deepening the black face lines on the face.
In other words, the coloring method of hook face in Peking Opera facial makeup is to outline eyebrows and lines with a brush dipped in color, and fill the facial color to become colorful patterns.
