Following the roars of "tiger mom" Amy Chua, Xiao Baiyou, a Chinese businessman, has recently stirred controversy on parenting in China by promoting his "wolf dad" approach in his book That's Why They Go to Peking University. The book touts how his "sticks make a great man" philosophy managed to send three of his four children to the prestigious university. Xiao's book has become a bestseller since being published on June 1.

Xiao claims to have spent 90 percent of his time and energy in parenting. With absolute authority at home, Xiao controls nearly every aspect of his children's lives, from cartoons, snacks, and pocket money to extracurricular activities and their friends. When Xiao's children were in preschool, they spent days reciting Chinese classics ranging from poetry to philosophy. If they failed to meet Xiao's requirements, they would be harshly beaten by their dad with a feather duster. The children could only go to bed after finishing all of their homework. Any violations of Xiao's rules resulted in physical punishment.

Xiao's methods have been challenged by many children, parents and education experts in the country. Some lawyers even warn that the approach may breach China's violence and child abuse laws.
