When Beijing won the bid to host the 2008 Olympics seven years ago, the city promised to host a unique Summer Games with the theme of "Green, High-tech and People's Olympics."
As the Olympic Games come to a close, some are wondering whether Beijing has fulfilled its commitment and if other countries are satisfied with our efforts.
Our reporter Zhen Chenguang has more.

It is an opportunity for countries around the world to gather to celebrate the Olympic Movement. Athletes and spectators have been inspired by the "faster, higher, and stronger" spirit that comes with competition. They have also been moved by peace, friendship and cultural unity.
More than a billion people watched the basketball game between China and the U.S.
An American reporter from ESPN sports channel, has this to say about the game.
"Millions maybe even a billion people watching it and talking to the American team before this game. They were all excited to be playing, and from the footage, they think it is going to be the biggest audience ever. You can feel the energy when you walk in, just to see the Chinese team and the passion for Yao [Ming]. Some other guys came and cheered for [American] Kobe Bryant. I think the energy is incredible."
Igor Grudin, the Russian women's basketball coach, also has high praise for the games. He says the quality service and high-standard hardware system have created better opportunities for athletes.
"The Beijing Olympic Committee has done a very good job. And all the volunteers, organizers and the audience as well have been left with a great impression. Besides, we have a very beautiful Olympic Village. With quality service and facilities, our athletes have made a lot of progress. Russian athlete Yelena Isinbayeva broke her own world record by jumping 5.05m to win the gold in the women's pole vault, and American athlete Michael Phelps made history with eight gold medals. What is more, Jamaican athlete Usain Bolt broke the 100m and 200m word records."
Du Shaozhong, Deputy Director of the Beijing Municipal Bureau of Environmental Protection, says due to various aggressive measures taken, Beijing had more days with excellent air quality during the games.
Giselle Davies, spokesperson of International Olympic Committee, says Beijing has fulfilled its commitments, and the IOC really appreciates the job it has done.
"There is a lot of misinformation sometimes on this question of promises. And we should remember exactly what was that like in the bid book which is ultimately the document where a city says this is what it will do. And in that, it was technically yes and showing how [Beijing] would welcome 28 sports, ten and half thousand athletes and the world's media. And in this regard, this has been delivered. We've seen fantastic sports venues, super sporting competitions; we've seen 20 thousand members of the media with Olympic spirits looked after here in the main press center. So the IOC will leave China feeling very pleased with how the games have been held and the sporting competition."
