Pu'er City

Nanzhao set a division called '''Bu'ri Jian () in 839 AD; this was the first time the region was integrated into the administrative system of a Chinese dynasty. In the Yuan dynasty, the central government changed the name to Pu'ri''' () in 1278. Finally in Ming dynasty, the name was changed to "Pu'er" () in 1384. The character of "er" () was changed to 洱 in Wanli Emperor period. The name "普洱" (Pu'er) has continued to be used to this day. Wa scholar Ni-ga states that the original name "Bu'ri" is the exonym of Blang people in Baraoke language, a dialect of Wa language, which means "my brother". Pu'er tea has the name "Pu'er" because Pu'er was the distribution centre of the tea produced in the south-west of Yunnan during the Ming and Qing dynasty. Pu'er tea became world-famous, and the city Pu'er also became famous as a result of the tea. The Yinsheng Festival was first established in the Nanzhao Kingdom of the Tang Dynasty. There were records of "Pu Tea" in the Ming Dynasty. ==History==

Its name was changed to Simao in 1950 following the Communist victory in the Chinese Civil War, while its surrounding county was known as Pu'er. In 2007, the town's name was changed back to Pu'er; the surrounding area became known as Ning'er County; and the name Simao was taken by a town and district within the city. The change had an effect on the size of the official Pu'er tea production area, a major regional product. The primary production area of traditional Pu'er tea, the forests surrounding Jingmai Mountain () in Lancang County, has been inscribed as a UNESCO World Heritage site. ==Geography and climate==
