Tickets 10 yuan. Tonganmen's city has been destroyed. There is an introduction to the ancient city of Shouchun on the upper floor. According to the examination, the south gate Tongyumen and the southeast corner are the Southern Song Dynasty city walls (1000 years of history), and the other sections of the city walls are basically the construction of Cai Guo and Chu Guo during the Spring and Autumn Warring States Period, so it can be said that the repaired part of the city walls are more than 1,000 years of history. The gate is the largest gate, and the gate is designed differently from the other three gates. The other three gates have different directions for the inner and outer gates, so the entrance and exit to the city are curved. The gate is a straight road.
