The blouse worn by women, that is, the upper pocket in the belly pocket, is named because it can't easily express the nature of people's clothes. In the Ming and Qing Dynasties, women's close-fitting clothes were mainly fastened, which were generally worn by maids-in-waiting, emphasizing embroidery decoration. It is a kind of "waist underpants" and the predecessor of "Chinese-style chest covering". Started in the Southern and Northern Dynasties, it was the title of underwear in the Tang and Song Dynasties. Its structural feature is to tighten the chest to prevent cold, which is used to restrain and fix the chest. Also known as Dou Du, square or diamond blocks are common, which can be divided into plain colors and embroidery. There are ropes at the left and right corners, tied at the back, with or without bags.

Different from previous dynasties, China ancient underwear had strict laws and regulations. To some extent, it can be said that coat is politics, while underwear is emotion. China ancient underwear is a perfect combination of emotion and art, and it is a static word in women's private space. When every ancient woman sews underwear, she will pour thousands of feelings: embroidered pomegranates for children, embroidered peonies for money, embroidered beasts to ward off evil spirits, embroidered grass for her sweetheart ... life ideals and personal desires that can not be reflected in the coat at all, but can be fully described and displayed in underwear.

As the book Yunxin Clothes-China Ancient Underwear Culture (published by Shanghai Ancient Books Publishing House) shows, the diversity and timing of China ancient underwear culture are more free, wiser and more affectionate than other clothes. During the Sui and Tang Dynasties, relying on underwear to express "the joy of sharing a room" and to act as an external symbol of stunning ladies-in-waiting, has begun to show the trend of "sexual openness" ... disrespecting the things in the boudoir, not being different ",revealing the body by virtue of the shape and color of underwear, showing the openness of underwear clothing culture and the extraordinary light of humanistic spirit in the Tang Dynasty. The restriction of "Neo-Confucianism" at the end of the Song Dynasty did not eclipse underwear culture, but "narrow, thin, long and strange" had its own characteristics in the Central Plains, which laid the foundation for the later "Chinese-style chest-wrapped" culture. In the underwear culture of the Ming Dynasty, the "waist-girding" underwear that "does not embroider red" and "does not wrap red" further reflected the concept of life consumption in the social fashion at that time and became a powerful symbol of resisting asceticism. The period of the late Qing Dynasty and the Republic of China was the sunshine period of China underwear. Whether active or passive, willing or unwilling, it not only inherits the traditional underwear, but also accepts the western underwear culture. The Chinese-style corset art of "shaping body" and "nourishing spirit" has promoted the brand-new connotation of China underwear. The scientific structure, idealized totem decoration, exquisite craftsmanship and diversified materials have made the Chinese-style corset art and society.

This book vividly presents the history, culture and design art of China's ancient underwear since the Spring and Autumn Period, and shows a romantic and secret image completely different from the rigor of China's ancient coat. Before the Han dynasty, women were naked, and it was not until the Han dynasty that they put on open-backed pants. "The Biography of the Queen Shangguan in Hanshu" said: "Although the imperial envoys are poor in pants, they bring more." The so-called "poor pants" are open-backed pants. The purpose of wearing open-backed pants is to facilitate defecation, but it is logical not to wear underwear. In this case, at least in the Tang Dynasty, the Japanese made the Tang suit into a kimono. It seems that women wear kimonos without underwear. Some people also say that kimono is the transformation of "five clothes", which comes from 800 boys and girls in Jiangnan. Women don't wear underwear, which keeps the basic characteristics of ancient people in China. "The only Japanese invention is the man's crotch cloth, which is still in the huge hip seam in sumo wrestlers."
