If you have learned mandarin for more than one year, your speaking still could not be well understood, you could not read and write in the language, we suggest that you would better to have a systematic learning with a professional teacher or an organization instead of learn on 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, private study. and what is more, the systematical learning is real, once it is learned and it would be a lifelong memory.
