2. The Lotus Inn Biexin Sword is a set of poems written by Wang Changling, a poet in the Tang Dynasty, when he relegated Jiangning (now Nanjing, Jiangsu) to the county magistrate. The first song is the author's farewell to Xin gradually drifting away at the riverside the next morning. The second song is the first night in the Furong Building to see Xin Xian off. The whole poem is full of emotion, scene blending, meaningful meaning and endless charm.
