Introduction to Langguan Alley: is located in the northernmost part of Three Lanes and Seven Alleys. During the Song Dynasty, a man named Liu Tao lived here. His descendants were all Langguan, and the name of the alley came from this. In the alley are Yan Fu’s former residence, Lin Shu’s Qinnan Academy, and the famous Ermei Bookstore, all of which exude a faint scent of books.
