Amy Chua's Battle Hymn of the Tiger Mother - especially its excerpt, Why Chinese Mothers are Superior - has sparked a debate over Chinese-style parenting and raised concern for two reasons:

First, the Chinese American author, mother of two daughters and a professor of law in Yale, has laid out the "ten commandments" for her daughters. For instance, the Chua sisters have to get A grades in all subjects and are not allowed to spend the night at any friend's place. Their mothers kept them focused on their studies, and didn't allow them to be distracted by extracurricular activities.

Second, this rigorous regime helps the Chua sisters shine in their studies. The elder sister is known for her piano recital at the Carnegie Hall, and the younger boasts an excellent academic record. And Amy Chua attributes her daughters' achievement to her Chinese-style parenting strategy.
