Description：The story takes place in ancient China. The Hua family has a pair of beautiful daughters, one named Ruolan (played by Jiang Ruolin) and the other named Yuhe (played by Liu Ziyan). When they grow up, their fates are different. Ruolan disguised herself as a man to join the army for her father, while Yuhe was selected into the harem because of her excellent singing and dancing skills. Ruolan, who joined the army for her father, had a tragic fate, and Yuhe, who entered the palace, was involved in the abyss of court conspiracy because of her competition for favor. Ruolan on the battlefield went through life and death, and fought with Yang Jun (played by Chen Sicheng) and Zhao Yu (played by Yuan Hong). While forging friendships, they also left behind an endless love triangle. Yuhe was trapped in the court struggle and could not extricate herself. Ruolan planned to rescue her from the sea of suffering, but Yuhe turned against her and even implicated her old father. Ruolan judged the situation and led the army to the expedition, but she embarked on a road of no return from then on. The grievances between sisters created a legend that will be passed down through the ages.
