Nonprofit takes the plunge to treat autism

A charity is providing a water-based therapy to help ease the condition. Nora Zheng reports from Hong Kong.

Two young men with autism, frightened and confused, stood beside a swimming pool, ready for their first scuba diving lesson. Suddenly, the older youth screamed, began punching himself in the head and dropped to the ground, rolling around in an uncontrolled fit.

That scene, from the summer of 2016, is etched in the memory of Chan Leung-bo, 52, former deputy chairman of the Hong Kong Underwater Association.
