There is an old mountain in Jiangbei, Nanjing, with green lungs in the city. It was originally an old mountain forest farm and now it is an old mountain forest park. Now it has become a new favorite for Nanjing people to travel in the suburbs. Around the old mountain, there are many tourist spots, such as Pearl Spring, Bulao Village, Ink Daxu, Buddha Lake, etc., which are a good place for people to relax on weekends. The main entrance of Laoshan Forest Park is on Huangshanling Road. From here, you can climb the mountain and overlook. The air environment here is very good.
