Teachers 庞 is a knowledgeable teacher.

Teacher 庞 is not only an knowledgeable teacher but also friendly and concerned about the student learning process.
The NihaoCafe is a good and useful feature in the language learning process. I am new at the school but I hope soon be able to know more about the NihaoCafe features and probably able to download the conversations to practice more.
I also think that Lesson Book is a good feature that should be included when join a course lasting several weeks. I think it should be less fancy in order to be more affordable and easy to carry .
