The largest city gate in the world !

WOW, it`s so great, i never see this before, Zhonghua Gate is the most imposing gate, still stands and is open for visits into cavernous hall.
Nanjing also have many other gate but this is the main gate and the city wall go through it which made a good military defense in Ming Dynasty.

The city wall was separated before because of city building, but now the government spent many money to put them together, which is looks exactly like the oranginal one now.
