Huzhanggou, Wutou Town, Xin'an County, was shocked to appear more than 2,000 meters of black dragon cave. On October 4, more than 20 members of the Xin'an County Writers Association and local historical researchers went deep into Huzhanggou Village, Wutou Town, the county to explore the Black Dragon Cave, and discussed the historical and cultural excavation of the Black Dragon Cave and the creation of cultural and tourism attractions.
The black dragon cave is located in the ditch below the slope of the east oil house of Hu Zhanggou Village Shen (Tang) Hu (Zhanggou) Road, the gurgling spring water in the ditch is continuous in all seasons, the soil and rock in the east of the ditch are as high as several zhang, there are ancient village ruins, people call the black dragon village. In the soil and rock below the wall, there is a meandering, more than 2,000 meters long soil cave. Because the hole is under the black dragon village, it is called the black dragon cave.
According to reports, the Black Dragon Cave was dug and built in the first year of Tongzhi in the Qing Dynasty (1862), when due to the corruption of the court officials, the country's internal and external troubles, and the people in the dire situation have risen up. There was the Taiping army in the south, and the Twist army in the north. In order to effectively defend against the plundering of the rebels and bandits, the Qing government ordered all localities to organize regimental training and build polders. It was under this historical background that Zhang Jingtian and Zhang Jingzhong, the squires of Huzhanggou Village, led the nearby villagers to spend two years to build a polder village on the earthen hill east of the black dragon pond in the ditch. At the same time, deep and long soil holes were dug under the wall. Because the village and the hole are located next to the Black Dragon Pond, it is called "Black Dragon Village" and "Black Dragon Cave".
Although the Black Dragon Cave is in the cliff, it is connected up and down, left and right. There are many forks in the hole, like a maze. There are living rooms, stove rooms, storage rooms, stone mills, wells, canals, traps and other facilities. The Black Dragon Cave not only has important historical research and regional cultural dual value, but also is a unique tourist attraction.
According to relevant experts, this is the only ancient three-dimensional military defense system that is the most complete in the country at present. And in the ancient village defense system on the mainland, such a close connection between the walled fort and the underground secret passage is also very rare in the country.
