16. Massive Olympic education campaign

Educating young people through sports is one of the primary goals of the Olympic Movement.

About 400 million young people in more than 500,000 schools across the country have received Olympic lessons ahead of the Beijing Games. More than 500 model schools have been named and a series of Olympic readers compiled and presented to students.

17. Highest number of doping tests

The anti-doping effort at the Beijing Games will be more extensive than ever, with as many as 4,500 doping tests, 25 percent more than in Athens four years ago and 90 percent more than in Sydney in 2000.

Tests will be carried out from July 27 at 41 test stations at the Olympic Village and all Olympic match venues.

18. Highest spending

The cost of the Beijing Games will dwarf the previous Olympics in Greece with total investment likely to reach $43 billion.

Venues, estimated to have cost about $1.8 billion to build, will be utilized as public sport and entertainment complexes afterwards.

Beijing also spent $16 billion in the past decade reducing smog, while additional infrastructure, such as the world's largest airport terminal, T3, an advanced railway station and new subway systems required vast expenditure.
