As is well-known, the nest was built in Beijing and is one of famous architects in the world. It is the first attraction for my Beijing travel after I settled down in a hotel. The audience capacity of the main stadium is1.5 times larger than the World Cup Soccer Stadium in Germany and twice larger than the main venue of the Athens Olympics back in 2004. The “bird nest” is the world's largest steel structure construction. After a "downsizing" and a removing of the roof and an expanding of the opening on the roof, the steel planned to be used come to about 4.2million tons.

The outlook of bird nest’s stand is a bowl-like design which surrounds the stadium that audience can have a clear watch at any position.

As I live in Tianjin, now I travel more and more frequently between Beijing and Tianjin. The one hour economic circle between Tianjin and Beijing has been set up so that tourists can live in Tianjin and tour in Beijing which is amazing and rare to be seen in other countries. This stimulates the development of Tianjin hotel reservation and tour industry of Tianjin as well.
