This will start with the origin of the "yellow jacket". At first, the yellow jacket was just a kind of clothes worn by the children of the Eight Banners riding inside. It is made of yellow satin, and the length of the clothes can only reach the waist and the sleeves can only reach the elbows, because riding requires a lot of intense movements immediately, and this design is also to facilitate people's actions. Before Emperor Qianlong, the Qing emperors rarely gave "yellow jacket", which generally existed as temporary clothes used by surrounding ministers when the emperor traveled. After the emperor traveled, he could not wear it, otherwise it would violate the laws of the Qing Dynasty.
In the Jiaqing period, the "yellow jacket" began to be awarded by the Qing emperor as a special honor to military commanders who had made great contributions, and as a symbol of royal glory. This way is generally called "giving yellow jacket". During the Taiping Heavenly Kingdom, there were too many Qing generals who made contributions, so there were many "yellow jackets" awarded by Xianfeng, but they were usually only awarded to ministers or generals who held important positions like Zeng Guofan and Li Hongzhang.
Finally, when Cixi was in power, the reward scope of "yellow jacket" was wider. As long as anyone can make Lafayette happy, Cixi will give that person a yellow jacket. For example, the train driver of Cixi was lucky enough to get this award. With the proliferation of yellow mandarin jackets and the shortage of silver in the Qing treasury, the Qing government began public auction. At first, it could sell tens of thousands of pieces of silver, but later, counterfeiting was rampant, and even butchers on the street could afford it. By this time, the yellow jacket had fallen to the point where 10 silver was not wanted, and it was ok.
