Nanshan is known as "the lung leaf of mountain city". What is even more rare is that in this forest closest to the city, natural scenery, historical humanities and anti-Japanese war sites are integrated. For example, Huangge Ancient Road, which has a history of 800 years, is the most famous ancient road in Chongqing and is known as the "Silk Road" in Chongqing. There is the Huangshan Anti-Japanese War Site Museum, which is the most complete preserved anti-Japanese War site group in China. The former site of the Kuomintang International Radio Station, the bomb shelter, the foreign soldier building, the former site of the British girls' school, Wang's former residence and other scenic spots are also connected in series by trails. Around 2008, Nan 'an District Tourism Bureau made statistics on the citizens who boarded the Huangge Ancient Road every day. No fewer than 1000 people climb the Huangge Ancient Road every day, and there may be tens of thousands of people on weekends and holidays. In recent years, Nanshan Trail has ushered in a more prosperous popularity. Mountaineering and fitness have become the pleasure of citizens' leisure, and the number of citizens climbing mountains has already doubled. These two paths will be repaired within this year. After Longjishan, Liangshuijing Trail, Qingshuixi Ancient Road and Huangge Ancient Road Phase I are put into use, the construction of the left (right) line of Huangge Ancient Road Phase II and Qingxiangting Trail will start on 20 12. The second phase of Huangge Ancient Road is about 3.6 kilometers long, and Line A is Chating-Laojundong-District No.4 Hospital-Chongwen Road; Line B is a fake road-waterworks-German Embassy-Wenfeng Tower-railway sanatorium-Chongwen Road; Line C is Waterworks-Huangjueya Street-Chongwen Road. Qing Xiang Pavilion Trail starts from Hao Yue Square in Longmen, with the left line leading to a tree and the right line leading to Laojun Cave. The remaining 14 trail will be completed in five years. At the same time, a new existing trail connecting road will be started, with four kilometers, Shangxin Street and Marble Stone as the three main entrances, forming a complete ring road in Da Nanshan area. These five paths were introduced by Zhou Xu, director of Nan 'an Tourism Bureau. The number of Nanshan trails increased from 14 to 19. The five new trails are: Cimushan Trail, Daxing Field Trail, Lijing Trail, Tushan Trail and Laolongdong Trail. Only Tushan Trail and Cimushan Trail have better road conditions. Among them, the Tushan Trail starts from Tushan Temple and ends at Tianmen, connecting Tushan Temple and Tushan Sculpture Park along the way, with good road conditions and steep slope. The Cimushan Trail starts from Cimushan Hot Spring City and ends at the Anti-Japanese War Site Museum. Along the way, it connects with attractions such as Cimushan Hot Spring, Huangshan Anti-Japanese War Site Museum, Wangjiang Pavilion and Cimushan Church, with good road conditions and beautiful scenery, which is suitable for all kinds of people. These four paths are relatively mature. It is recommended to take these roads to climb the mountain. Huangge Ancient Road has a history of 800 years and is the most famous ancient road in Chongqing.
