In Beijing opera, the flag inserted on the back of Wu Sheng is called "leaning on the flag". What is its main function?

Shit, it's the general uniform of a military commander. Round neck, tight cuffs. Look at the identity before and after, which is long enough. "Depend" originated from the military uniforms of general officers in Qing Dynasty. Connected from top to bottom, it has the dignity and generosity of a long and wide robe, but it is divided into two pieces, like clothes and clothes, like armor and armor. Although the clothes have armor patterns, they are not close to the body, thus completely getting rid of the original form of life. Extreme exaggeration and deformation make this "separated" costume endow the characters with mighty spirit, while the movements are convenient for exaggerated dance movements. The style of the play clearly embodies the artistic characteristics of Beijing Opera costume "dance". The main pattern is fish-scale or T-shaped, the middle of the fish-scale is decorated with the group initials, and the periphery of the nail pattern is decorated with double decorative patterns-"small side" and "big side", which are the continuous patterns of Caolong and Jiangya respectively. The pattern of the belly is also very important. Generally speaking, Wu Sheng or Wu Laosheng used "double dragons to play with pearls" or "single dragons". Wu Hualian's character is rough and bold, and he often uses a big tiger's head. The colors are also divided into upper five colors and lower five colors, and the color specifications are roughly the same as Python's. For example, black is a black face, green is a red face, and white is a handsome martial arts student and martial arts student. When using it, men lean on the flag (the living basis of leaning on the flag comes from the command flag of ancient generals, which is bigger, more beautified and more exaggerated than the command flag), indicating that the characters are fully armed and in a state of war, which is called "leaning". The structure of the backrest is very complicated. Whole body embroidery 3 1, of which 3 pieces can be used for other purposes. People wearing pythons or arrows are surrounded by collars, symbolizing military commanders; Using only two legs is a symbol of the loss of helmet and armor of defeated soldiers, which is symbolic. Soft leaning is called "soft leaning" and is used for military commanders in non-combat situations. \ The overlord depends on Xiang Yu, and the overlord of the place of Chu. Black Ping Jin embroidery is characterized by a yellow "net nail" at the lower end of the abdomen. The court drama "Overlord Examination" in Qing Dynasty embroidered the elephant trunk with square nail pieces, which has been eliminated. The woman's abdomen is slightly smaller, embroidered with double phoenix peony. There are two or three streamers under the abdomen. Tiger head and tiger shoulder (shoulder nail board) lined with lotus leaf sleeves and embroidered phoenix peony. Use the cloud shoulder when using. Its clothing style is more decorative than men's couches, with more gorgeous colors and patterns, which perfectly sets off the heroic and feminine image temperament of female generals.
