Since some people have posted stuff about wanting to find a good tutor, I can recommend two people. They both have a lot of experience (one was my own Chinese teacher), their pronunciation is perfect, and they’re pretty flexible in terms of the hours they teach and teaching you exactly what you want. If you want their contact info, PM me or post a reply. I would suggest only serious students need contact me, as their rates are higher than most Chinese tutors (with good reason).
