The largest city gate in the world !

<p>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.<br /> 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.</p> <p>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.</p>
