It is said that Chinese-style chest covering is when Yang Guifei and An Lushan are having an affair. An Lushan accidentally caught the red seal on Yang Guifei's chest. Yang Guifei was afraid of being known by Tang Xuanzong, so she took a piece of red silk and wrapped it around her. Xuanzong not only didn't see the red sign, but also was very happy and thought it was beautiful. Since then, this method of wearing has gradually become popular, and there is such a thing as a Chinese bra. So Chinese-style chest covering began to spread from Yang Guifei.

It is said that An Lushan recognized Yang Guifei as a foster mother at that time. On one occasion, An Lushan entered the palace, first visited Yang Guifei, and then visited Tang Xuanzong. Emperor Xuanzong was very angry, so he asked An Lushan why. An Lushan replied that the Turkish courtiers visited their mother first and then their father, so An Lushan became Yang Guifei's adopted son.

Rumor has it that An Lushan has a full face of beard and is also a man who is good at scheming. Therefore, this person is very capable and can be favored by Yang Yuhuan. Being so ugly was also angry with Yang Yuhuan, who took advantage of his relationship with Yang Yuhuan to gain military and financial power. Historically, the relationship between the two was ambiguous. Since Yang Guifei was recognized as a foster mother, An Lushan has often been free to enter and leave the harem, even at night. Moreover, there are some historical records. For An Lushan's birthday, Yang Guifei dressed An Lushan in a big bathtub according to etiquette, which shows that their relationship is extraordinary.

Chinese-style chest wrapping is the product of An Lushan's cheating with Yang Guifei. Yang Guifei not only looks good in it, but also has great charm. Gradually, the pattern of Chinese-style chest covering became more complicated, and until now, there is still the popularity of improved Chinese-style chest covering.
