What does the ancient crane Chaoyang case mean?

Since ancient times, people have regarded "Xianhe Chaoyang" as a symbol of good luck, health and longevity. China people's worship of cranes is not only unusual, but also branded with human nature and personality. In the simple belief of primitive people, the magical power of cranes is reflected. For example, in the folklore "crane fairy", it is said that cranes guard the harmony and tranquility of the kingdom of birds; In "Danhe Sows Green", it is described that cranes descend from the sky and sow barren land with reed seeds; In Zhalong Lake and Red-crowned Crane, the appearance of thousands of birds in the crane house was praised, the trapped dragon was saved, and the long drought on earth was lifted. The "immortal" of the crane highlights the rationality of Taoism in China. Taoism regards cranes as messengers of gods, and it is a great leap for crane culture to turn from nature to gods. The "immortality" of the crane is more noble when displayed in the court, which has auspicious meaning, blessing function, symbol of honesty and protection of imperial power. At the beginning of this century, six tall and lifelike bronze cranes were unearthed in Qin Huang's tomb, indicating that he still wanted to become immortal through cranes after his death. From the Ming Dynasty to the Qing Dynasty, first-class civil servants embroidered cranes, and the court regarded cranes as "under a bird, above ten thousand birds", which was a symbol dedicated to the royal family after dragons and phoenixes. In addition, the crane is not useless in the eyes of courtiers, but a symbol of integrity and honesty.
