A stricter style of parenting is the Authoritarian type, where parents expect a lot from their children while disregarding their children's own wants and wishes. A parenting style in which children assume greater power over their parents is the Permissive style. In this style, children get what they want and get away with most mischief. It is generally believed that the Authoritative parenting style is likely to produce emotionally balanced and well-disciplined children, as it banks on co-operation as opposed to skewered power relations between the two parties. In the case of Amy Chua's personal story (which is representative of Chinese Americans in general), her two daughters were brought up to excel in both academics and arts. And she was able to achieve this by imposing strict controls over her daughters' personal, family and social lives. For example, both Sophia and Louisa are seldom allowed to indulge in extracurricular activities, get any grade other than an A, and be able to master musical instruments at a young age. Behind this grand ambition for her children, there goes a lot of hard work from all involved. And it is due to this kind of strictly regimented, industrious and highly ambitious life-stlye imposed on her children that they were able to achieve so much success in such a short time.
