Liu An, the king of Huainan in the Western Han Dynasty, was fascinated with alchemy at first. He recruited more than 1000 alchemists to conduct experiments in his mansion. Legend has it that he cultivated into an immortal, and his whole family, including chickens and dogs, soared. But the fact is, he was killed for treason, and Liu Xiang copied the secret recipe of his family's alchemy.

Liu An's nephew Liu Che, that is, Emperor Wu of the Han Dynasty, likes alchemy as much as his uncle. Half of "Historical Records of Xiaowu" tells how he prized the alchemist and found the fairy medicine all his life.
