Zhao Guorong, 59, shows a photograph of her with her son Zu Wenbao, then aged 10, at Tiananmen Square on a National Day holiday, at their home on the outskirts of Beijing, China August 21, 2022. Zu is one of the 14 million people in China who have autism spectrum disorder, a developmental disability caused by differences in the brain. Despite laws to ensure the integration of people with autism, many in China know little about the disorder and support remains lacking, experts say. REUTERS/Tingshu Wang
