The Olympic is coming in 18 days and the Chinese people are doing all they can to hold a successful event. On 19 July, Beijing opened three new subway lines to ease traffic during the Olympic Games.
They are :
the Airport Line
Line 10
and the Olympic Branch Line
These three lines are expected to significantly expand the capacity of the city's underground transport and therefore ease the traffic jam. The price for line 10 and the Olympic Branch Line is 2 yuan and price for the Airport line is 25 yuan. If you are going to the National Stadium or the Bird’s Nest but don’t know how to get there, there will be no need for you to worry about getting lost! The subway lie will take you there directly. Of course, it’s better to know something about Beijing. echinacities.com would be a great help! It covers information of almost every aspect of the Beijing city. Preparing before hand is better!

Those 3 new subway lines will certainly make travelling alot easier in the big city of beijing.
