I am from Texas in the United States, My son shows great interest in Chinese language and Chinese culture, he offer says that he will go to China for live and work when he grows up, I think I should respect his wishes and ideas, and I need to do something for him to help improve his Chinese language skills, I Googled and found many online course, apps and site are providing teaching service, I don’t know which is the best and effective, do you have any suggestion ? How can I choose the right way for my Kids to learn Chinese language, any suggestion would be greatly appreciated!
