HOME to 26 different ethnic nationalities,southwest China's Yunnan Province covers an area of 394,000 square kilometers, on 94 percent of which stand mountains and plateaus. At 6,740 meters above sea level, the province's highest point is the Meili Snow Mountain's Kawagebo Peak. Its lowest, where the Honghe River runs into neighboring Vietnam, is just 76 meters above sea level. Yunnan also has an extremely variable climate. The mountains in the northwestern part are snow-covered all year round, while well-known Xishuangbanna Prefecture enjoys a tropical climate. The weather is most volatile in the mountains, where the four seasons seem to collide and interchange every couple of miles.
