The eight immortals are the eight Taoist immortals widely spread in Chinese folklore.
Among the eight immortals, there is a cynical, crazy but not crazy begging immortal named LAN Caihe. Shen Fen's biography of continued immortals in the Southern Tang Dynasty, Taiping Guangji in the early Song Dynasty, and Lu You's book of Southern Tang Dynasty all contain his deeds, which were born from the late Tang Dynasty to the Five Dynasties. LAN Caihe has no fixed place to live. He is a cosmopolitan. His behavior is eccentric. He likes to drink and sing. He usually wears a broken blue shirt, one foot wears boots, and the other foot is naked. What is more unusual is that in summer he wears cotton padded clothes, but in winter he lies in the snow and his whole body emits heat (continued biography of immortals). At ordinary times, he holds a large bamboo board of more than three feet. While playing the bamboo board, he walks singing and begging along the street. He sings many songs, most of which are born from touching the scenery, which not only makes the world feel unfathomable, but also has fairy meaning. One of them said: how can the world be like when LAN Caihe sings a song? When a girl is young, she throws a shuttle. The ancients never return. Now more people come one after another. When they ride a phoenix to the blue waves in the morning, they see white waves in the mulberry fields in the evening. The long scenery and bright light are in the sky, and the gold and Silver Palace is high and steep. Lan Caihe is crazy. Some people give money to him, and he mostly gives it to the poor.
It is also said that lancaihe was born as a barefoot immortal and traveled around the world. Some people have seen him in childhood and old age, and his face remains the same. Later, when he was drunk in Haoliang restaurant, he suddenly rose into the clouds, threw down his boots, belt and board, and walked away.
