Introduction to Eunuch Lane: Eunuch Lane is an alley parallel to the south of Guanqian Street. It is known as "eunuch lane for eating evil" due to the concentration of food restaurants. As early as the 1930s, there were restaurants such as Zhengxingguan, Xuangong, Sanwu, Da Xinyang, and Jue Lin Vegetable Food Forest. Especially after the reform and opening up, the eunuch wine shop industry has become increasingly prosperous and is known as the "Food Street". Deyuelou, Wangsi Restaurant, Shanghai Laozhengxing, Yuan Dachang, Gongdelin and other restaurants stand side by side here.
