White Collar Boxing has only recently arrived in Beijing since it started in the United States. Thecompetition has been staged annually since 2008.

It essentially takes non-boxers - mostly white-collar professionals -and gives them the chance to punch each other for a cause.

The matches benefit a Shanghai nonprofit called Leo's Foundation,founded by Scott and Cecile Spirit, organizer and co-founderShane Benis says.

"They had premature babies in 2008," he explains. "They werecared for in Fudan University's Children Hospital's neo-intensivecare unit, and they caught wind that some families couldn't affordthe healthcare. So they started a foundation to help pay for the careof premature babies."

White Collar Boxing has donated more than $200,000 to thecharity, also known as the Foundation for Newborns withRespiratory Failure, its website says. Benis and WCBC are nowworking to found a similar foundation in Beijing.

While the events are bilingual, the proportion of local fighters is inthe single digits. But many overseas Chinese participate.
