One look at the busiest subway stations in Guangzhou will tell the story: the Asian Games are here.
Intense-looking armed police, standing motionless on 20cm-tall platforms, guard every exit of Gongyuanqian station which leads to Beijing Road, the city's busiest shopping area. In Xiaobei station, populated mostly by African traders, six male and two female unarmed police cadets patrol tirelessly.
With the 16th Asian Games starting tomorrow, Guangzhou's security forces are on high alert to ensure a safe and smooth opening.
As organisers of the world's largest non-Olympic multiple-sports event in terms of the number of participating countries, Guangzhou faced a management and logistical challenge, while the rest of the world watched.
This year, there will be 11,643 athletes from 45 countries participating in 42 sports and a total of 590,000 volunteers for the Asian Games and Para Asian Games. About 10,000 journalists from around the world will cover the sporting spectacle.
Fifty-three venues are dotted across the Pearl River Delta. Although most are located in Guangzhou city's downtown area - Panyu, Huangpu and Huadu districts, there are others in Foshan, Dongguan and Shanwei, and even county-level cities such as Zengcheng and Conghua .
