Can you tell me whether the Zhenyuan Escort Agency is in the south or the north?

I remember that in any martial arts novel or in a certain computer game, this resounding name was mentioned - Zhenyuan Escort Bureau. Invincible, the bandits will be frightened when they hear it! Is this town far away from that town? Is the world-famous Zhenyuan Escort Bureau hiding here? With this strong doubt, I embarked on a journey to find the former escort agency. Starting from Guiyang, the capital of Guizhou Province, we headed south along the Hunan-Guizhou line. Soon we came to a small town surrounded by green water and reflected in clear mountains. This is the destination of this trip, Zhenyuan County, Qiandongnan Miao and Dong Autonomous Prefecture, Guizhou Province. After entering the county town, I walked through the streets and alleys, looking for where the escort bureau was in the past, hoping to catch a glimpse of its style. The county is not big, but streets and lanes extend in all directions, with convenient land and water transportation. The buildings on both sides of the streets and rivers are also very distinctive. Their styles are very different from those in the mainland. The three- and four-story houses are adjacent to each other but not connected to each other. , the two floors are about 50 centimeters apart. It is said that this is to avoid the tragedy of burning the joint venture. Although the current buildings are all brick-concrete structures, the design and architectural ideas and concepts of that year are still followed. Data show that Zhenyuan is a national key historical and cultural city with a history of more than 2,200 years. There are many historical sites in the city and more than 70 key cultural relics protection units at all levels. Among them, the Qinglong Cave, an ancient building group, is even more famous and famous all over the world. Buddhism and Taoism culture are integrated into one. It is built close to mountains, rivers and cliffs. It is ancient and unique. In addition, at Feiyun Cliff, known as the first cave in southern Guizhou, historical celebrities such as Wang Yangming in the Ming Dynasty, Lin Zexu, and He Shaoji in the Qing Dynasty left their traces here. There are many inscriptions on the cliff that remain today. It is now a key cultural relic protection unit in Guizhou Province.
