Introduction to Jiangjun Cave: "Jiangjun Cave" is a coal cave dug by General Xu Shiyou, the founding general of the People's Republic of China. In the mid-20th century, General Xu Shiyou served as the commander of the Nanjing Military Region, defending the southeast. During the Cultural Revolution, he led engineers and Nanjing students to station in Baohua Mountain, excavating Jiangnan coal fields, and vowed to "transport coal from the north to the south." Jiangjun Cave was the coal mining tunnel at that time. .
