A 1,080-km (670-mile) section of the Qinghai-Tibet railroad is currently under construction from Golmud to Lhasa. It includes the now completed 3,345-meter Yangbajain No. 1 tunnel which is 4,264 meters above sea level and located 80 km NW of the regional capital Lhasa. The 815-km section from Xining to Golmud in Qinghai opened to traffic in 1984.
More than 960 kilometers, or over four-fifths of the railway, will be built at an altitude of more than 4,000 meters, and over half of it will be laid on frozen earth.
The railway's highest point, the Tanggula Mountain Pass, is 5,072 meters above sea level.
Thirty railway stations are to be built, among them Tanggula Mountain station, which at 4,500 m will be one of the highest-altitude railway stations in the world (after Cóndor station, at 4,786 m, on the Rio Mulatos-Potosí line, Bolivia, and La Galera at 4,781 m in Peru).
Rail-laying in Tibet was launched in double directions, towards Tanggula Mountain and Lhasa, at Anduo Railway Station on 22 June 2004. When the railway construction is complete (expected in 2005; signalling and track testing require another 6 to 12 months), it will be possible to travel from Lhasa to Beijing in 48 hours. The railway will later be extended to Xigaze (to the west) and Linzhi (Nyingchi, to the east).
The Great Wall of China
The Great Wall of China ( Pinyin: Chángchéng), also known in China as the Great Wall of 10,000 Li¹ ( Pinyin: Wànli( Chángchéng), is an ancient Chinese fortification built from the end of the 14th century until the beginning of the 16th century, during the Ming Dynasty, in order to protect China from raids by the Mongols. It was preceded by several walls built since the 3rd century BC against the raids of nomadic tribes coming from areas now in modern day Mongolia and Manchuria.
The Wall stretches over a formidable 6,700 km, from Shanhai Pass on the Bohai Gulf in the east, at the limit between China proper and Manchuria, to Jiayu Pass in western Gansu province in the west, at the limit of the Gobi Desert and the oases of the Silk Road.
The Wall was made a UNESCO World Heritage Site in 1987.
In 1938, Richard Halliburton's Second Book of Marvels stated that the Great Wall is the only man-made object that can be seen from the moon. This statement has persisted, assuming urban legend status and sometimes entering textbooks. If taken to mean that the Great Wall can be seen with the unaided eye from the distance of the moon, it is untrue.
Beijing ( Hanyu Pinyin: Be(iji-ng, Wade-Giles: Pei-ching; Postal System Pinyin: Peking), is the capital city of the People's Republic of China.
Beijing is one of the 4 municipalities of the People's Republic of China, which have a provincial-level status, and is under the direct control of the central government. Beijing has been a municipality since the beginning of the PRC.
Beijing is one of the largest cities in China, second only to Shanghai as the nation's biggest in terms of population. It is also a major transportation hub, with dozens of railways, roads and expressways connecting the capital city in all directions. Currently Beijing is recognized as the political, cultural, and social center in the People's Republic of China.
