Chen Sinan, a local who runs a company that offers tailored rainforest hikes, has been busy recently, especially since many parents are traveling with their children during the school winter vacation.

Xishuangbanna is located in Yunnan's far south. It's widely known as a "wonderland of plants and animals" and as a home to wild Asian elephants. It is where several ethnic groups inhabit for generations.

"Visitors also want to know about tropical forests," says Chen, whose tours are fully booked until the beginning of March.

"Many parents also hope their children will learn about nature while having fun."
