When the Qing Dynasty fell, Chu and his villager friends became bandits, only to be recruited by a warlord.
There, he was discovered by a Japanese spy, who wanted him to be a body double of Puyi, by then the Emperor of Manchukuo.
Eventually, Chu found out about the Japanese's deeds, and decided to leave his life as Emperor.
He was separated from his family members while they were escaping, and Chu eventually ended up in Hong Kong as a beggar.
