In 1912, Gou Sheng, a farmer from Zhili, was purified and sent to the Forbidden City by his father. He changed his name to Laixi and became the last eunuch of the Qing Dynasty. He was cautious and cautious within the palace walls. In the era of collapse of imperial power, warlords' melee, and Japanese invasion of China, he went from a "living fossil" in the Forbidden City to a "disabled person" expelled from the palace. In the fireworks of the streets of Peking Hutong, he depended on the widow Xiu'e, and struggled to pursue the dignity and integrity of "humanity" amidst the shackles of identity, emotional entanglements, and the catastrophe of the times. This is an epic story in which an individual who has been "castrated" by the times finally reaches reconciliation with himself and his destiny in the ashes of troubled times.
