I got another suggestion.. I noticed in your micro classes (which are great btw) there is a very important part towards the end of the video lesson where you put your teaching to work in a real life setting, whether it be with venders or Bobo for instance. I think you should continue this in other lessons because in real life, people don’t actually talk slow or put emphasis on each word.. so I think it would help us speak more “real” fluent Mandarin if we could hear how people use it in their day to day lives.
