Zhang says the art town is free for families with autistic children and the ticket revenue on Dec 23 will be donated to the China Social Welfare Foundation for autistic children.

Zhou Jing, the executive director of the autistic children rescue fund, says the park's offer is a good opportunity for families with autistic children to mix with other families in a relaxed atmosphere. "Some parents of autistic children told me that they really enjoy playing with their kids in the art town. I hope there will be more outdoor activities of the same sort for such families."
