I'm a native Chinese speaker and have been teaching mandarin for over 2 years. Some of my students have passed HSK level with very high scores. I also speak fluent English and am learning Portuguese as well. So communication for me won't be a problem. The schedule for the class will be dependent upon the students. I can also work with the company who do need a Chinese speaker for the business. Any other information you need from me, just send me a message.
