Judging from the hairpin ornaments left by empresses in Qing Dynasty, there are two kinds of hairpin. One is a practical hairpin, which is mostly used to fix the bun and head shape. The other is a decorative hairpin, which is made of precious materials with exquisite patterns and is specially used to comb the bun and wear it in an obvious position. Many realistic palace paintings collected in the Forbidden City now depict queens wearing hairpins. From the picture, some of them put the hairpin in the middle of the bun, and some inserted it obliquely at the root of the bun. Empresses' heads are full of jewels, but their hairpins are the best. Therefore, in the Qing Dynasty, empresses and concubines were all made of jade jewelry, and their production techniques were also very particular. It is often the most precious to make a hairpin with a whole piece of jade, coral crystal or ivory. For example, the white jade in the Forbidden City in Beijing is made of a pure suet white jade, and the hairpin is the last stroke of the birth word. Similarly carved jade plate sausage hairpin and coral bat hairpin are excellent works of hairpin decoration. In addition, there are Jin Fu Qian Guan, Magpie Hairpin and Five Bat Shoushou Hairpin, which attract people's attention because of their exquisite carving and exquisite production. There is also a kind of head hairpin inlaid with various pearls and gems on a gold base, which is mostly composed of a head and a pin, but it still has a sense of wealth and luxury. With the gradual widening and expansion of the queen's hairstyle in Qing Dynasty, the modeling of hairpin ornaments has gradually developed to two extremes. One is that the hairpin head gradually becomes smaller, such as a pimple needle, an ear-digging spoon and an old crow spoon. The other is that the hairpin ornaments are getting bigger and bigger, which are not only suitable for Manchu women to comb two heads and cover a large area, but also gradually evolve into headdresses, flat squares and other big jewelry.
