The crane is elegant and refined, and the red-crowned crane is called a crane by the ancients, which means longevity. As an auspicious bird, the ancients regarded it as a sacred mountain. Familiar idioms, such as tortoise crane prolonging life and pine crane in Changchun, are all related to cranes. Therefore, cranes are auspicious birds in people's minds, representing longevity and auspicious details, symbolizing peace, prosperity and people's happiness. Crane has a characteristic, that is, patience and persistence, which also reflects the persistent spirit in China culture.

There is an idiom called "driving a crane to the west", which is a euphemism for the death of a very old person. So this idiom can't be used indiscriminately. The ancients began to use the saying of driving cranes westward to seek death in Taoism. Before Taoism appeared, cranes were auspicious symbols of time. It is said that the crane is the mount of an old fairy family, and people are good at associating beautiful meanings, so it has been brought to the extreme among folk customs. Therefore, there are cranes in the west, and they swim in the water to express their blessings to the dead. Crane's temperament is mild, which is more in line with the overall thinking of Taoism. After the establishment of Taoism, many ancient books recorded the embryonic form of immortals by riding cranes, which gradually became a fashion. In ancient China, people were deeply influenced by Buddhism and thought that people would be in the western paradise after their death, so they died and were called traveling westward by crane.
