Medog, with an average altitude of 1,200 meters, is located in the lower reaches of the Yarlung Zangbo River. Because of the poor traffic infrastructure in the past, Medog was once known as an "isolated island" on the plateau. 

Eight years ago, Zhang Chunhuan, a young man from Shanxi Province, came to Medog. At that time, the traffic in the county located at the southern foot of the Himalayas was inconvenient. Zhang had to walk three or four hours from some townships to the county seat to buy daily necessities. He never planned to make his home here one day.

Nowadays, Medog has schools, shops and restaurants. A beautiful park has been built in the center of the county seat. It has become a tourist attraction in Tibet and an agricultural products base featuring tea, Tibetan medicine and characteristic agriculture. In 2019, Medog shook off poverty.
