Overall, it is still very good, mainly to see the local dangerous terrain and remember the British. Standing on the city wall, you can see the surrounding terrain at a glance, and you can also feel why it is called the Sanjin throat place to visit. Personally recommend spring and autumn tours, the vision will be better, many projects in winter have been stopped or closed. Also, when you go, you must pay attention to the map of the scenic spot. There are two doors in the scenic spot. It is easy to go wrong or wrong, so you must look at the map of the scenic spot. Overall good!
