"To me, when you see a child showing marked improvement, this is the kind of feeling I can't really describe, better than having a paper in a top scientific journal," Keith Kendrick, a British professor who focuses on child autism research at the University of Electronic Science and Technology of China (UESTC) in Chengdu, said passionately. He has worked and lived in Chengdu for ten years.

Although there is currently no front line treatment for children with autism, Kendrick and his team have done a lot of research and clinical trials over the years, trying to help these "children of the stars" as much as possible.

He said that his team had achieved very good results in the trials earlier last year, where about 40 percent of the children showed improvement. "It's encouraging, but we're not there yet. There's a lot more to do," he said.
