Tengchong

Tengchong is a county-level city of Baoshan City, western Yunnan province. It is well known for its volcanic activity. The city is named after the town of Tengchong which serves as its political center, previously known as Tengyue in Chinese. English language sources of the late nineteenth and early twentieth centuries use names such as Tingyueh, Teng Yueh, Momein, and Momien, these last two from the name for the place, one of the formerChinese Shan States, in the Shan language.

It borders with Myanmar in the northwest for 151 km (94 mi). By road, it is 650 km (400 mi) west of the provincial capital, Kunming, and 170 km (110 mi) westward from Baoshan's urban area.

Tengchong marks the southwestern terminus of the Heihe-Tengchong Line.
