A history of guarding national security, a history of the world's richest man. Such an ancient city wall, with Chiang Kai-shek, Shen Wansan, Jubao Pot, Yuanyuan, Zhu Yuanxuan, the Japanese army invading China, is connected. Jubao, to gather wealth, cultivate morality, filial piety. Applying for a world heritage site, catching up with the free publicity explanation (maybe the merchant), the explanation is interlocking and fascinating.

It is best to find a like-minded person, walk on it, measure completely the length, so that you don't have to go to the city. 5A Scenic Area!
