What does it mean that the crane and Kirin are together?

1 should mean a prosperous career. In ancient China, the official costume of a civilian was a crane, and that of a military attache was a unicorn.

2. The white crane is a fairy bird in Taoism, and Taoist Antarctic immortals often walk with cranes. For literati, cranes not only represent longevity, but also represent nobility and elegance.

Kirin is a legend, which only appears in the era of peace and prosperity. People think that Kirin has great wisdom, and its shape is combined into one, like deer body, legs and hooves, but it is scaly, with a head like a dragon's head and a tail like a lion's tail. Sometimes a pair of horns on the head gives people a sense of majesty, so the military attache uses Kirin.
