"The nourishment from classical Chinese culture made an impact on their understanding of life," Sun says of a summer camp on traditional culture his children attended last year.

Sun then made the decision to move his home from Beijing to Xuzhou in East China's Jiangsu province, where his children joined Huaxia Xuegong, a school that focuses on traditional art and culture. His children have now developed an interest in Chinese literary classics, traditional paintings and musical instruments.

"My children attend the school, my wife teaches handicraft there and I am a volunteer, teaching two music classes every week."

With his youngest daughter Aibo, who will turn 7 in September, Sun is making a cartoon series on Chinese literary classics.

Many of China's ancient crafts are dying gradually, but he says he hopes they won't disappear entirely.

"I hope more people will learn about them and pass them on to future generations."
