www.yangers.com for Yangshuo. Good fun. Get bikes. Ride bikes along the Li River and then put bikes and kids on the bamboo rafts (yes they have life jackets). Paddle in the river with water buffaloes. Chase fireflies. Join the kids at Tai Chi. Watch the taffy puller at the day market. Kids can't wait to get back. (PS the hospital there is really welcoming - boys plus bikes)
