April 2 is World Autism Day, and children with autism are also called "children of the stars". They are like stars in the sky, twinkling alone in the distant and dark night sky.

Autism is a developmental disorder characterized by severe loneliness, lack of emotional response, language development disorders, stereotyped repetitive movements and other reactions. Survey data shows that there is one autistic child in every 50 children in the United States, and one in every 100 people in my country has autism, which means that there are at least 13 million autistic patients in my country. In order to raise people's awareness of autism and strive for early treatment to improve the condition of patients, the United Nations General Assembly passed a resolution in December 2007 to designate April 2 each year as World Autism Day.

April 2, 2020 is the 13th World Autism Awareness Day. Relevant data show that there are about 76 million autism patients in the world, especially the incidence rate is rising sharply globally. The number of autistic patients in China is also increasing. According to statistics from the National Census of Disabled Persons, childhood autism ranks first among mental disabilities in China. It is estimated that there are more than 1 million children with autism in China and the mainland, and the prevalence is increasing year by year. However, more people may not be diagnosed with autism.
