Where does the story of driving a crane to the west come from?

The word "Traveling westward with a crane" comes from the legend of Wang Xizhi, a calligrapher in the Eastern Jin Dynasty. Wang Xizhi closed his door in his later years and devoted himself to reading and writing. On the fifth day of the fifth lunar month, his son, Wang Xianzhi, came to the shore of Jianhu Lake in Huiji. He met a monk and gave a trust to Wang Xizhi. Wang Xizhi opened it and read it. The letter said, "At noon in Duanyang, I will go home by crane, break all my troubles and visit the Queen Mother." After reading the letter, Wang Xizhi walked to Jianhu Lake. There is indeed a white crane by the lake. Wang Xizhi rode on the white crane and flew into the blue sky. Later, people only regarded the death of a highly respected person as "traveling westward with a crane". In ancient China, cranes were often regarded as a symbol of longevity, which was greatly influenced by Buddhism. Buddhism believed that people would be in the western paradise after death, so it was compared to "driving cranes to the west". As an auspicious spirit bird, cranes are accompanied by immortals.
