In the meantime, the place suitable for going out to play is the outdoor area. Although some parks in the city are still open, there are still quite a lot of people, and it is still not suitable to go from the point of view of reducing the density of people. Speaking of where to play now, I recommend three places: Jingmen Railway Walking Jingmen Railway —— was built by Zhan Tianyou, the father of the railway, in 1906. It has experienced a hundred years of wind and rain and is one of the earliest railways. Jingmen Railway is a branch line of the famous Beijing-Zhangjiakou Railway, which transports the coal from Mentougou to Xizhimen for the steam locomotives of Beijing-Zhangjiakou Railway. With the suspension of the last train, the Jingmen Railway has not run for some time, and it has become the best choice for railway enthusiasts to walk. Jingmen Railway starts from Jingmen Railway Square and goes all the way to Muchengjian. The existing railway is nearly 40 kilometers, which is difficult to walk in one day. It can be divided into three sections. Th—— is closed during the period, while Luopoling is operated by Fengsha Railway Station. You can go around, but it&;s good to play in three sections. It is said that in the planning of Jingmen Railway, the S4 line of Beijing Suburb Railway will be reopened, and there is not much time to walk the railway. I want to go as soon as possible.
