At the end of the Ming Dynasty, feudal emperors believed in geographical geomantic omen, and thought that only when the mountains were long, continuous, tall and majestic, and the places surrounded by mountains and waters had good geographical geomantic omen, would talents with good writing and high martial arts rise up and call on the people to resist the court. Therefore, the court often sent Mr. Feng Shui to dig holes and cut mountains to control the Long Mai of Feng Shui. They saw the Chahe River, a place that started from the main peak of Miaoling, winding and magnificent, surrounded by mountains and rivers, with green mountains and green waters, for fear of people who were unfavorable to the Ming Dynasty. In order to prevent the Miao people from rebelling, the imperial court organized the imperial court and local governors to visit Chahe River for pulse detection and dragon treatment three times. This is the first time that the local governor has visited Long Mai. After many explorations, it was determined that the "Dragon" crossed the small circular slope raised in the middle of Chahe Village, went to the small ravine at the foot of Zhazhai, then went down to the ferry at the mouth of Chahe River, and went 300 meters upstream of Qingshui River, and crossed the pole in a straight line. This dragon is very cunning. Sometimes in the mountains and sometimes in the river, it can't find the key points of "dragon cave" and "dragon governance", so it has to plant a cypress tree as a mark in the middle of the stockade, at the foot of the stockade and at the ferry, so it was reported to the court. The second time, the imperial court sent dozens of people to Chahe Village for exploration, and determined that Long Mai passed the end of the mountain at the head of the village to the small round slope raised in the village, then to Xiaoyangkou at the foot of the village, and finally to the mountain pass at the intersection of Qingshui River and Chongan River 20 meters away. As a result, the dragon changed a lot and could not find the key point of healing. So we planted camphor trees on the above four points as markers, drew a map and reported it to the imperial emperor.
The thorny problem of "dragon" in the Chahe River often makes the emperor fidgety. The emperor summoned the most famous and experienced general Hai, Kang's adult and two important officials to study together, and used the best tools and methods to get rid of the "dragon" in Chahe River. So, General Hai and Lord Kang led 3,000 people to Chahekou with "Dragon Horn". Playing "Dragon Horn" to tease dragons reveals the main points. They listen to the "dragon" responding on the south main slope when they play the trumpet on the rain-praying slope, and listen to the "dragon" responding on the rain-praying slope when they play the trumpet on the south main slope. Finally, they blew the horn on the camphor tree at the foot of the village, and the sound of dragons came from both sides of the hillside. Two kilometers away from Chahe village, there was a cry of little dragons, and the dragon caves of the two big dragons also gave off purple light, but there was no light at the dragon caves. At this time, General Hai and Kangda found two big dragons and one little dragon. After finding the dragon cave, they decided to get rid of the two big dragons that had an influence on the court first. So, the soldiers divided into two ways, dug a big round pit with a diameter of about 20 meters and a depth of about 20 meters at the foot of Nangan Mountain and Qiyushan Mountain, about 1000 meters away from Chahekou, put a lot of tung oil into the pit, and then put a lot of lamp grass into the oil pit, and lit the "sky lantern" for 749 days. In order to verify the effect of "dragon" therapy, General Hai and Lord Kang sent troops to visit villages hundreds of miles away. After hearing the news that chickens don't bark and dogs don't bark for 49 days, they didn't retreat until they knew that Long Mai's excavation had been completed. Since then, Chahe Village has left three cypress trees with 3. 1 min and four camphor trees with 4. 1 min. Nanganpo and Qiyupo left two big pits, which became the scenic spots of Chahe Village. This small village, 2.5 kilometers south of Chahe Village, was named Xiaolongzhai.
