Wang said he first gave his child a cold shower when he was 15 months old. After years of chilling experiences, he rarely falls ill and has developed much stronger willpower than his peers, according to Wang Shaoyan.
"He has never taken any sick leave from kindergarten," he said, proudly.
However, some parents find his methods too extreme.
"I'm not sure a 4-year-old is prepared for such intense training," said Zhang Ruxia, a woman who gave birth to two boys in October in Tianjin. "You can have good intentions to train your child at an early age but you also have to consider whether he can take it."
Wang responded by saying children are too young to make decisions, and it is up to parents to lead them on the right path.
"I read many materials before (I started training my son), and the whole process is step-by-step, without pushing or imposing on my son," Wang said.
The father said he was not acting rashly but following a scientific way of education. He said the queries and doubts about his methods reflect the declining standards of modern education.
