Speaking of the city gate, in the history of China's five thousand years, there are many famous city gates, sui tang luoyang yangcheng palace ziwei palace south gate "Ying Tianmen" is known as one of the most famous "seven days of architecture" in Luoyang, Ying Tianmen was first built in the first year of Sui Daye (605), initially called Zetianmen, and later changed to Ying Tianmen in order to avoid Wu Zetian.
Luoyang, which was once the capital city, has many city gate buildings, dingding gate of gucheng road in Luolong District of Luoyang City, Lijing Gate in Luoyang Xiguan, four city gates in xi'an, east, west, south and north, and the most famous Beijing Tiananmen, but there is one city gate that is the largest city gate in China, and it is also the best-preserved and most complex fortress urn city in the world, known as "the first urn city in the world".
This city is one of the thirteen Gates of the Ming Dynasty capital city of Nanjing, the Zhonghua Gate, which was once the southern gate of the Southern Tang Dynasty capital Jiangning Province and the Southern Song Dynasty capital Jiankang Fu City, which began to be built in the second year of the Ming Dynasty (1369) and was not expanded until the eighth year of Hongwu (1375).
Zhonghua Gate, all of which can be called "the world's first urn city", but also because of its geographical location, inside and outside the gate there is the Qinhuai River runoff across the east and west, the south side of the traffic connection Changgan Bridge, the north side connected to the Zhenhuai Bridge, is the Nanjing traffic artery at that time, in the early Ming Dynasty to guard here, the use of a strict inspection system.
When it was built, each brick was printed on the side with the names of brick makers and supervising officials, if you found unqualified, Ming Taizu would not easily let you go, but at the beginning of the construction, the Zhonghua Gate was not called Zhonghua Gate, but called Jubao Gate, as for why it was called so, it was also because of the grudge with Ming Taizu and Shen Wansan.
During the Hongwu period of the Ming Dynasty, the construction of the Zhonghua Gate was just started, and as a result, an accident occurred in the middle of the repair, the foundation of the city gate suddenly fell, and the entire city gate collapsed, ming Taizu was very angry after hearing about it, and believed that the construction officials cut corners, so he personally supervised, and also carved a name on each brick, so that no one dared to fake it at all.
But when the Zhonghua Gate was halfway through construction, it collapsed again, and even Ming Taizu felt strange, so he went to ask Liu Bowen to count a gua, and Liu Bowen told him that there was a monster under the Zhonghua Gate that specialized in eating the foundation, and a cornucopia must be buried under the city gate to suppress the monster.
And this cornucopia just happened to have one in Shen Wansan's hand, the foundation of the early Ming Dynasty was still unstable, Ming Taizu was very jealous and afraid of the property Ofeshen Wansan, if Shen Wansan took advantage of the emptiness of the national treasury, suddenly there would be trouble, Ming Taizu also wanted to cut Shen Wansan's financial resources, by the way, to test.
Ming Taizu ordered the expropriation of Shen Wansan's cornucopia, and after borrowing the cornucopia, it was buried under the foundation of the city wall, and the result was really in response to Liu Bowen's words, after the cornucopia was released, the Zhonghua Gate was really not collapsing. After 600 years, zhonghua gate encountered the Taiping Heavenly Kingdom and suffered from Japanese artillery fire, but it still stood.
