language is one of the most powerful weapons that you can use to reach the heart of people. The premise is that you have gotten the best and most authentic part of the language.

If you have learned Mandarin for more than one year, your speaking still is not well understood, and/or you are not able to read and write in the language, then we suggest you to start a systematic learning program with a professional teacher or an organization instead of learning on the street with an amateur or nonprofessional native speaker. A professional tutoring means a systematic learning, a variety of delivery modes to prepare for a mandarin learning experience: seminars, lectures, project work, tutorials, and private study. On top of all of that, the systematic learning is real; once it is learned it will be a lifelong memory.
