Enclave is a special phenomenon of human geography, which refers to the land that belongs to an administrative region but is not connected with the local area. This geographical pattern is common in the world, and they all have to fly over other regions or countries to manage their own land. For example, Kaliningrad, Russia, which is about 380 kilometers away from Russia, is surrounded by Lithuania and Poland, one of which is in the Baltic Sea. The geographical position of occupying Leningrad is extremely important, and it is the frontier of Russia against the West. There is also a world-famous enclave in the United States, namely Alaska in the northwest of North America and Canada with the same roots as the United States.

Alaska has a total area of 17 1000 square kilometers, which is larger than many countries in the world and is the largest wasteland in the world. So today, let's take stock of some famous wasteland in China. The first line is the North Third Line in Langfang City, Hebei Province, which is surrounded by the capitals of Beijing and Tianjin. If you come here from Hebei province, you must go through Beijing or Tianjin to get there. The North Third Line has a total area of 1.277 square kilometers and a total population of over one million. It is composed of three county-level units, namely, sanhe city, Xianghe County and Dachang Hui Autonomous County, and belongs to Langfang City, Hebei Province. Beisan County is one of the fastest-growing areas in Hebei Province, known as the "Houhuangyuan" of Beijing, and it is the first choice for migrant workers across provinces in Beipiao. At the junction of Guizhou Province and Hunan Province, there are also two magical wasteland, belonging to Dihu Township, Tianzhu County, Guizhou Province.

Although Dihu Township belongs to Guizhou Province, it is not connected with Guizhou and is surrounded by Hunan Province on all sides. Therefore, the communication between local residents and Hunan Province is very close, but if they want to go to other parts of Guizhou Province, they must cross Hunan Province. Dihu Township is 55 kilometers away from Tianzhu County, but only 25 kilometers away from Huitong County, Hunan Province. Dihu Township covers an area of about 30 square kilometers, and most of them are Miao people. This administrative pattern was formed by land sales between two provinces in history. In today's counties, Guizhou people and Hunan people are mixed together, of which 2/3 are from Guizhou and 1/3 are from Hunan. They live in harmony, and there will even be a row of houses and house numbers in two provinces. In fact, there is a smaller land in Tianzhu County, but this land belongs to the jurisdiction of Hunan Province, and this land is as big as a village. Hunan and Guizhou provinces can be said to have you and me. There is also an interesting wasteland in Ningxia Hui Autonomous Region, which is Wenpu Township, Longde County, Ningxia.

Wenpu Township is not connected with Ningxia, but goes deep into the border of Gansu Province, with a total area of about 82 square kilometers and a total population of 1.7 million. Wenbu Township is the most populous township in Longde County, with beautiful scenery and terraced fields all over. It is also the famous hometown of clay sculpture in China, which has produced many famous clay sculpture artists. The formation of Wenbu County is mainly due to the repeated division of Ningxia and Gansu, and the two provinces in some areas are closed alternately. In addition to the three northern counties, there is also an interesting enclave in Hebei Province, Shexian County. In the hinterland of Shexian, there is a place where all Tianjin residents live, and it also belongs to the jurisdiction of Tianjin, which is more than 500 kilometers away. A local iron and steel plant, once called Tianjin Iron Works, is now called Tiantie Metallurgical Group, with a total area of about five square kilometers and a total population of more than 20,000.

The dual-core farm covers a total area of 380 square kilometers, of which gannan county and Meris districts each account for about half, with a total population of about 1. 1 10,000. Shuanghe Farm, formerly a dual-core labor camp, was founded in 1956. It mainly accepts reeducation-through-labor personnel from Beijing, and most of the local staff are Beijingers with Beijing hukou. Shuanghe Farm shoulders the dual responsibilities of transformation and production. The local jurisdiction belongs to Beijing, but the land ownership still belongs to Heilongjiang Province, where the terrain is flat and the land is fertile, which is very suitable for agricultural planting. Beijing has opened up a green agricultural production base here, built a modern state-owned large farm with mechanized planting, provided a large number of organic and green healthy foods for the market, and made great contributions to the agricultural development of fertile land. In fact, China's wasteland is far more than that. There are some interesting and unknown stories behind every wasteland. What else do you know?
