It means good luck in officialdom and smooth career.
Among the costumes of the Qing Dynasty, official hats are closely related to the official system of the Qing Dynasty. Official hats are the most obvious external manifestation of official positions at all levels, that is, official hats are the most important grade symbol of officials in the Qing Dynasty. One of them is also a symbol of officials' rights.
The official hats of the Qing Dynasty had strict hierarchical connotations, which was reflected in the decorations on their official hats. The first is the crown on the crown, which can also be called the crown bead, but it is actually a gem. This was an important symbol for distinguishing the grades of officials in the Qing Dynasty. The so-called top quality refers to the top bead on the crown. The top bead must be worn according to the rank of the official. After replacing the Ming Dynasty, the Qing Dynasty implemented a strict nine-level official system, and formulated nine different patterns of court uniforms. It also specified nine different gemstones, gold and silver as the tops of official hats to distinguish the high and low levels of officials. For example, the crown of the emperor's hat is made of gemstones, while the crown of the first-class official's hat is made of ruby. In fact, the higher the status, the more precious the material of the crown worn by the hat is.
