Bayi orChagyib (Chinese:八一街道;Tibetan:བྲག་ཡིབ་གྲོང་) is a subdistrict inTibet Autonomous Region, China and seat ofBayi District,Nyingchi. It lies on theNyang River at analtitude of 2,994 metres (9,826 feet). Bayi is an important timber and wool producing town, known historically before the 1960s asLhabagar. By road it is 405 kilometres (252 mi) east ofLhasa on the way toChengdu.[1][2]
The new subdistrict completely absorbed the ancient village ofDrakchi, which used to stand on this site. The Bayi Zanchen bridge crosses the Nyang-chu orNyang River here.[3]
Following the tranquil liberation of Tibet in 1951, thePeople's Liberation Army commenced the construction of roads and bridges, establishing cities in the region. Consequently, people from the surrounding areas gradually relocated, and "Lhabagar" evolved into a significant transportation center inTibet.[4] To honor the contributions of the PLA, the residents of Linzhi transformed this location into Bayi New Village, which subsequently evolved into Bayi Town ("Bayi" signifies the anniversary of the establishment of the People's Liberation Army).[5]
There are 9 villages under the jurisdiction of the subdistrict, with a total population of 21,400, from the Han, Hui, Mongolian, Xibe, Manchu ethnicities. The subdistrict covers an area of 55 square kilometres (21 sq mi), with an area of 51,047mu (3,403 ha) of cultivated land. There has been the extension of two major irrigation channels in the subdistrict to provide for rice farming and the production of other cash crops.
Bayi has asubtropical highland climate with monsoonal influences (KöppenCwb). Precipitation is abundant compared to other areas in Tibet and the area around Bayi is covered with trees.[6]
