How many counties and districts are there in Erenhot? Thanks!

There are three sub-district offices: Wulan, Dongcheng and Xilin (administering 14 community committees) and Saiwusu Science and Technology Park, Grile Aodusumu (administering 4 animal husbandry gacha and 1 ecological immigration area). In 1992, the city had 47 party and government agencies and 49 public institutions. In 1999, the Education Bureau and the Science and Technology Bureau were established; in 2003, the Gesumu Party Committee, the Government, and the National People's Congress were added. In the same year, it was divided into the Construction Bureau, the Land and Resources Bureau, the Agriculture and Animal Husbandry Bureau, the Forestry and Water Affairs Bureau, and separate functional departments such as the Civil Affairs Bureau and the Ecological Office. The urban location, urban population, and area are adjacent to Sunit Left Banner in the east and Sunit Right Banner in the south and west. After the administrative region was restructured in 2003, the area under its jurisdiction expanded from 162.8 square kilometers to 4015.1 square kilometers, with a border length of 68.29 kilometers. The current built-up area of ??the city is 18 square kilometers, with 298,000 hectares of available grassland, 325 hectares of cultivated land, 3,396 hectares of forest area, and a total population of 100,000.
