7. Largest number of host cities
To help host a successful Games, six cities in China have joined Beijing as co-hosts. Tianjin, Shanghai, Qinhuangdao in Hebei province and Shenyang in Liaoning province will stage some Olympic soccer matches.
The coastal city of Qingdao in Shandong province will host the sailing regatta, while Hong Kong, a city with a long history of horse racing and matching first-class facilities, will play host to equestrian events.
8. New sports
To modernize the Games, the IOC will introduce two new sports to the Beijing Games: Bicycle motocross (BMX) and the 10km marathon swim.
BMX will offer two gold medals in individual men and women's competitions.
Marathon swimming will be held in Shunyi Water Park and offer two gold medals in individual men and women's competitions.
Owing to limited participation worldwide, softball and baseball are expected to make their final Olympic appearance in Beijing after being axed from the London program.
9. Cheerleaders
Some 600 cheerleaders from all over the country will go all out to entertain spectators with Chinese folk dancing, acrobatics, drum shows, lion dancing and martial arts during time-outs. Cheerleaders were selected from national Olympic cheerleading competitions and local clubs.
