The Chinese are very generous when it comes to educating their children. Some parents send their children to the best schools or even abroad to England, the US or Australia, regardless of how much this costs. Many also want their children to take extra-curriculum activities (课外活动) where they either learn a musical instrument or ballet, or other classes that will give them a better start in life. The Chinese believe that the more expensive an education is, the better it is, so parents often spend a large amount of money on education. Even poor parents manage to buy a computer for their son or daughter.

In fact, most parents fail to see that the best education they can give their children is usually very cheap. Parents can see that their children’s skills are different; they will usually be skilled in some areas while poor in others. However, they fail to realize that today’s children are lack (缺乏) of self-respect and self-confidence.

The problem is that parents are only educating their children on how to take exams and how to study effectively. They are not teaching them the most important skills they need. They do not teach them to be confident, happy and clever.

Parents can help achieve this by teaching their children practical skills like cooking, sewing and other housework.

Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and finish his job step by step. The result, a well--cooked dinner, will give a child a lot of satisfaction and confidence. All these will help the children step to success in the future.

An old machine such as a broken radio or TV set that you give your child as a toy may make him curious and arouse(唤醒) his interest. If he will spend hours looking at it, and try to mend it; your child might become an engineer when he grows up. Such activities do more than teaching a child to read a book. They teach them to think and to use their minds. This is much more important than learning by reading a book.
