Zhen Yurao, the biological sister of Zhen Huan, was born to yearn for the freedom of the mountains and wilderness, but due to an incident involving the Zhen family, she was forced to enter the palace with red walls. The once-romantic girl became a prisoner in the palace wall. In the undercurrent of the harem, she gradually learned tactics and established influence from a passive bystander to survive, and transformed into a chess player who could control the turmoil in the harem.
She fell in love with Prince Yunli of Guo County, but was trapped in the imperial power and family responsibilities. She reluctantly broke off the relationship and was trapped in the whirlpool of power. She and her sister Zhen Huan went from complete dependence to conflicting ideas. After experiencing suspicion and conflict, they finally reached reconciliation over the years.
After holding power and being firmly at the center of the harem, she was not coerced by glory and glory, so she resolutely gave up her position as Queen Mother, established the Jingxin Hall to protect the fallen palace family members, and wrote the "Records of the Deep Palace" to preserve the past events of the harem. Throughout her life, she was torn between power and her true heart, but she kept her soul intact and wrote a harem legend that belongs exclusively to Zhen Yurao.
