As Wen was overseeing preparatory work in western and southern Beijing, about 8,000 technicians were busy testing information services for the Games in the Digital Beijing Building, a comprehensive information facility in the city's north near the National Stadium, or Bird's Nest.

They are to provide technical services for 31 competition venues, 15 non-competition venues and venues in co-host cities in upcoming five days.

"There is no second chance for us. Once the Games start, our work has to be successful," said Yang Yichun, director of the BOCOG Technology Department. "We are confident of technical support."

On the street near the Bird's Nest, a police motorcycle escort team was launched on Sunday to lead the way for Olympic-related vehicles and cavalcades.

South of the Bird's Nest, Han Rubing and her family were getting their home ready as one of the Olympic home-stay families.

She and her husband had been improving their cooking skills.

"I hope my home can be a small window for foreigners to learn about China and the Chinese," said the university teacher.

Meanwhile, thousands of miles from Beijing, the Olympic torch started its three-day relay in southwestern Sichuan Province, which was devastated by the May 12 earthquake.

At the first stop Guang'an, people shouted "Go China" and "Go Sichuan" after one-minute silent tribute for earthquake victims.

Sichuan will be the last stop before the torch reaches Beijing.

Premier Wen Jiabao shoots a hoop at the Beijing Olympic Basketball Gymnasium, where he met with the Chinese men's team August 3, 2008. He talked to NBA star Yao Ming, and wishes the team the best for the Games.
