From the perspective of art and craftsmanship, the jade seal of the Han Dynasty was well-made, rigorous in its composition, and round in its strokes. Because jade was hard and difficult to be cut by a knife, it produced a special "cutting knife method" of "straight down with a flat knife". Because the jade was not easily corroded and damaged, the jade seal could retain its original appearance. The words on the surface of the seal were exquisite. At first glance, the strokes were square and upright, but there was no sense of stiffness. It presented a solemn, elegant, condensed, stable, ancient, and beautiful style, giving people a sense of harmony, glory, and nobility. In the entire jade system of the Han Dynasty, the jade articles of the Han Dynasty inherited the tradition of the jade articles of the Warring States Period and developed. The techniques of jade processing were improved. There were more high embossed and round carvings, more patterns of holes and fine lines on the surface, and the surface polishing techniques of embossed and plain jade articles were improved. Jade seals, as one of the imperial seals, also reflected the development of jade craftsmanship in the Han Dynasty. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

During the Warring States Period and the Qin and Han Dynasties, official seals were the main seal. According to historical records, after Qin Shihuang unified China, there was a clear difference between the official seal and the official seal of the Warring States Period. The emperor called it the seal alone, and the seals used by other officials were generally called "seal" or "chapter". Since then, the seal had become a symbol of power. There was a strict hierarchy for wearing seals, especially official seals. The size, texture, ribbon, and color of the seal were determined by the size of the official position and the amount of salary. Thus, it could be said that the royal seals of the Warring States Period and the Qin and Han Dynasties were mainly official seals.
