Another issue may be non-native bees being trucked around in huge quantities and randomly deployed, which is something I've seen a lot of over the last 15 years. I've interviewed the beekeepers and a fair number of them come from as far away as out of province (eg. Sichuan). There's a fair chance they compete with naturally established native bee colonies for food, possibly carry diseases to them, or even fight.

Chengjiang at the north of the lake has recently established a new sewage and runoff treatment and filtration system partly based upon a series of ponds and reed systems and extensive gardens along the foreshore. This helps to reduce the intake of detritus carried in post-rain flash flooding due to runoff. Assuming that system works as advertised, then the biggest issue Fuxian faces is not shampoo, but agricultural runoff. So far it has not had an algal bloom like northern Dianchi, but perhaps this is mainly because of its size and depth. Certain parts of the lake water near agricultural outflows are definitely polluted, with intensive chicken farming visible almost on the water in one case. Another big polluter is the military, who maintain a submarine base and a number of large ships which spew oil across the water every time they are operated.

THE NATIONAL GOVERNMENT SHOULD SEND A TEAM OF INSPECTORS AND RESOLVE THE PROBLEMS, THE LOCALS ARE INCAPABLE.

The article and comments are misleading.

A'Chang are spread out all over western Yunnan: "Baoshan prefecture, Longling and Tengchong counties; Dali Bai autonomous prefecture, Yunlong county; Dehong Dai-Jingpo autonomous prefecture and Baoshan district, Liangge, Longchuan, Luxi, and Yingjiang counties, Myanmar border area." www.ethnologue.com/language/acn + en.wikipedia.org/wiki/Achang_language + en.wikipedia.org/wiki/Achang_people

According to Wikipedia, Husa is the least linguistically and culturally intact of all A'Chang areas. "Speaking a distinct dialect, the Husa Achang (戶撒) living in Longchuan County (also in Dehong) consider themselves to be distinct and filed an unsuccessful application in the 1950s as a separate nationality. The Husa were more Sinicized than other Achang. For example, Confucian-styled ancestral memorial tablets are common in Husa homes. Most traditional Husa believe in a mixture of Theravada Buddhism and Taoism."

Much of southern Sichuan and much of Yunnan traditionally speak Tibeto-Burman languages, and this is a linguistic term and not a genetic one. The group includes languages such as Yi (China's and Yunnan's most numerous minority) as well as almost every other Yunnanese minority (Hani, Akha, Lahu, Nusu, Lisu, Sani, etc.). Many of these groups (as well as other minorities in Yunnan, like Tai speakers) have oral histories supporting migrations southwest from southern Sichuan, Guizhou or Guangxi, much of which is now well attested linguistically or genetically.

Even discarding linguistic evidence, given that the major events in Yunnanese history (usually invasions from the northeast: Chinese, Mongols, etc.), regional history (frequent invasions of the Red River delta) and regional prehistory (destruction of the Shu Kingdom of Sichuan during the Han Dynasty, to suggest the A'Chang "came from" or are "descended from" Burma is completely spurious.

Also note that the Bo people's area of the Sichuan/Yunnan borderlands was part of the culture the Chinese refer to as the Shu/Ba culture, which was a peripheral culture beneath the main Sichuan plains (various Shu kingdoms) that were conquered by the Han Chinese in the Han Dynasty. Period descriptions of Sichuan were essentially rainforested jungle with elephants, peacocks and other fauna... you can read more in the Classic of Mountains and Seas ... en.wikipedia.org/wiki/Classic_of_Mountains_and_Seas

Also in the Han Dynasty, onf ot the impassable steep rocky precipices of the area was bored through by a Zhuge Liang, thus opening a relatively direct and defensible route to Yunnan.

Also nearby (also my pics on Wikipedia) was the amazing hanging tombs of the Ku people at at Bainitang (白泥塘): en.wikipedia.org/wiki/Hanging_coffins ... the Ku people are said to have moved down from the Jinsha River Rock Art (金沙江岩画) area, where the Bo people still exist but no longer have the habit of making new cliff tombs. This makes the Ku people the last cliff tombs builders in Eurasia, as far as my research can tell. Amazing stuff, and really out of the way / hard to find. Great adventure finding them!
