The Chinese parents dancing on live streams to help their children fight cancer

Every night, a group of parents in Shandong live-stream themselves dancing for hours until they can no longer keep going. Their children are patients at Shandong Cancer Hospital, and many are in an advanced stage of their illnesses. Cancer treatments in China can often cost hundreds of thousands of yuan. So, for these parents, dancing for an online audience at night has become one of the few ways they can raise money and still be able to spend most of their daytime hours tending to their sick kids.
