Jenny Bowen, an American living in Beijing, was selected as the only American to carry the 2008 Beijing Olympic torch on Chinese soil．She and seven other non-Chinese winners had been chosen from 262 applicants from 47 countries in a contest organized by Chinese computer maker Lenovo Group and the official English-language newspaper, China Daily．When Bowen ran with the Olympic torch, she was not only representing the United States, but also representing thousands of Chinese orphans (孤儿).

Bowen, a mother of two adopted (收养) Chinese daughters, is director of Half the Sky Foundation, an organization which was founded in 1998 and aims to enrich the lives of orphaned children in China．In nearly 10 years, Bowen and Half the Sky have touched the lives of over 13,000 children．Half the Sky is now present in 36 welfare institutions in 28 Chinese cities． About 4,000 children are active in the program, which provides trained staff, educational tools, medical support and care for orphans.

Bowen hoped that running with the Olympic torch would help draw attention to the children in China．She was among 19,400 runners who carried the flame along an 85,000-mile, 130-day route across five continents．Beijing organizers say it was the longest torch relay in Olympic history.

Like Bowen, the seven other non-Chinese winners, including a German engineer and a Venezuelan designer, live in China．Other countries represented were the Philippines, Colombia, India, Japan and Russia.

According to Olympic organizers, candidates (候选人) were selected based on an online vote, committee selection, their “love of Chinese culture and history” and devotion to “communicating information of a real China to their native countries”．Each runner carried the torch for 200 meters on Chinese soil.
