Due to his family's financial difficulties, he was the last in his class to buy a camera.

"I realized later that my mother might have used money for her treatment to buy me a camera," he said. His mother died of disease in 2012. Wang regretted not taking a family photo when she was alive. That prompted him to consider taking photos for families living in poverty.

Wang and several other students decided to do it together. They chipped in to buy print paper and other photography equipment and also collected plastic bottles, old books and newspapers from student dormitories to raise money.
