Kailu County

Kailu County (Mongolian: ᠺᠠᠶᠢᠯᠦ ᠰᠢᠶᠠᠨ; Chinese: 开鲁县) is a county in the east of Inner Mongolia, China. It is under the administration of Tongliao City, 76 kilometres (47 mi) to the east, and China National Highway 303 passes through it.

As the traditional seat of Ar Khorchin, East Jaruud and West Jaruud, the 3 areas are abbreviated in Chinese as the 3 R's since each contains the word R transcribed as "LU" in Chinese. The 3 R's was then known as the 3 Lu's as well. In 1905, with the slogan of developing the 3 R's (開發三魯), the city took the name of such abbreviation and was named 開魯 (KAI LU).

Kailu County is made up of 10 towns.
