About Beijing:Beijing (北京 Běijīng) is the capital of the most populous country in the world, the People's Republic of China. It was also 
the seat of the Ming and Qing dynasty emperors until the formation of a republic in 1911. Beijing is the political, educational and cultural centre of the country and as such it is rich in historical sites and important government and cultural institutions.The city is well known for its flatness and regular construction. There are only three hills to be found in the city limits (in Jingshan Park to the north of the famous Forbidden City). Like the configuration of the Forbidden City, Beijing has concentric "ring roads", which are actually rectangular, that go around the metropolis.

Foreign visitors to Beijing can usually afford to take a taxi everywhere they want to go. The price ranges from 10 - 35 RMB for most destinations. Airport can set you back up to 140 RMB. Still, when you convert it back into local currency is still cheaper than most places in the world. The main problem is communication. Be prepared to have your destination written in Chinese characters to hand to the driver. English is almost non-existent and even place names all have their own unique Chinese name.
