The grandson of Emperor Wu of the Han Dynasty and the son of Liu Kun, the king of Changyi, inherited the throne at the age of 6. He was supported by Huo Guang as the deposed emperor of Han at the age of 18. He was deposed 27 days later, demoted to the title of Marquis of Haihun at the age of 29, and died in depression at the age of 33. He has experienced the four identities of king, emperor, marquis, and citizen in his life. He is the only special person in Chinese history who combines these four identities. He is called Liu Momo because of archaeology. How do you choose to be Liu He when you travel through time?
