Lhasa means 'sacred land' in Tibetan
Lhasa is the capital of China's Tibet Autonomous Region. Lhasa has a history of more than 1,300 years. It is the political, economic, cultural and transportation center of the region. With a population of 400,000, Lhasa covers an area of 30,000 square km, in which the downtown covers 544 square km and holds a population of 140,000. Tibetan ethnic group makes up 87 percent of the total population; the rest consists of Han, Hui and other ethnic groups.
Located at the center of the Tibet Plateau and the bottom of a small basin surrounded by mountains, Lhasa has an elevation of 3,650 meters. The altitude results in the low atmosphere pressure and less oxygen contents in air. However, the wet summer makes the air pressure comparatively high, and is the best season for visitors.
The Lhasa River, known as the "merry blue waves," runs through the snow-covered peaks and gullies of the Nyainqentanglha Mountains, extending 315 km. The river empties into the Yarlung Zangbo River at Quxu, forming a scenic wonder that features blue and white water waves. Inside the city towers the Potala Palace. The city combines traditional and modern features, including prayer wheels and computers.
Lhasa has cool summers. In July and August, the daytime high temperature is a little higher than 20 degree C (68 degree F), and in the night temperature will follow to about 10 degrees C (50 degree F).
