The "Wolf Daddy" Xiao Baiyou is a 47-year-old Guangdong businessman who deals in real estate and luxury goods in Hong Kong.

Just as the "Tiger Mom" controversy started simmering down in China, here comes the "Wolf Daddy." Xiao Baiyou, a self-proclaimed expert on strict parenting, is sparking a new round of fervent discussion on child-raising methodologies among anxious Chinese parents.

He insists he's the best parent in the world. This past June, Xiao Baiyou published a book on parenting that featured a severe method -- spanking.

He laid out his spanking introduction in his book "Therefore, Peking University Brothers and Sisters," and so he quickly became nicknamed the "Wolf Daddy". His favoured method is the rattan cane, and he spanks his children's calves and hands when they break his rules. His strict methods appear to have had good results: his four children have entered Peking University, one of the top universities in China.

So Xiao proudly spreads his education idea that children need to be disciplined, ruthlessly. In his microblog, he said, "Come on, want your children to enter Peking University without spanking and scolding them? Don't be ridiculous." And, "Leave your children more money, and spanking as well."

But the "Wolf Daddy" method was soon questioned by other parents. Some speculate that Xiao Baiyou just want to be famous through propagandize his strict child-raising rules.
