Lao Mendong, an ancient place name in the southern part of the old city of Nanjing, is located at the intersection of the hoop barrel lane and scissors lane of Nanjing's Confucius Temple. It belongs to the national 5A class tourist attraction. Old streets and alleys make people feel the southern style of the old city. After visiting the Vanguard Bookstore, we continue to walk in. There are traditional snacks in Nanjing, as well as the familiar Deyun Club and various traditional crafts. Along the way, we can see many street sculptures and appreciate the exquisite stone sculptures on the archway. In addition, there are many pavilions and pavilions, which seem to have the characteristics of gardens in the south of the Yangtze River. It's really good to come here to take a view.
