After the Forbidden City's gorgeous clothes and pearls faded away, An Lingrong and her sisters disappeared into the misty rainy boat in the south of the Yangtze River. The sound of the abacus in the Suiyu Pavilion, the incense burner in the Shirong Pavilion, and the smell of green grass in the medicine garden weave their new daily life. However, the shadow of the past has not dissipated, and there are also slight waves in the business world in Jiangnan. The rumors of the silk merchants are as sticky as the plum rain, and the temptations of Caobang are like the undercurrents of the river. They no longer hold swords, but respond with a more calm attitude - An Lingrong's incense burner is filled with wisdom, Meizhuang's account book is playing with the edge, and Nian Shilan's laughter defuses the fight. There is no bloody storm, only sisters working together to protect this hard-won world while resolving crises one after another. They turned the strategies of the deep palace into the wisdom of life. In the streets and lanes of Jiangnan, they wrote another kind of "killing and decisiveness" - overcoming strength with softness, smoothing waves with warmth, and guarding their homeland with heart. See how they turn their thrilling past into a smooth and smooth rest of their lives.
