If you want to learn Chinese then let me tell you that it is not an easy task. As we all know that the things that have many benefits are hard to achieve same is the case with the Chinese language. The best way to teach him Chinese language is to speak it as much as you can. It does not matter if you speak a little incorrect, until and unless you will not speak wrong you cannot be corrected by your teacher or by other people. Another good idea is to take interest in the history of china so that you can know everything about the past of the language. Them you can apply that information in your learning experience of Chinese language. Make sure that you have a good teacher who has the power to explain you with good examples these are few things that you can do.
