Lane introduction: Today's Miao King City is called "Dehuixian" in the Miao language of Guzhai, which means Xinzhai. It is the place where the Miao King lived and is also the relic of the ancient battlefield. During the Ming Dynasty, this was the center of the Miao people in the Laershan area; in the early Republic of China, there were still more than 230 families living there. Each household in the lane has its own dragon (front) door and back door, which are connected to each other and can be checked step by step, just like a Bagua maze. After an inspection, experts on ancient cultural relics unanimously agreed that the city was designed to be "able to attack, defend, and retreat." It was a Miao king's city with a considerable level of military construction and fortifications. Its architectural structure and construction fortifications can reproduce the history of hundreds of years ago.
