Must I keep to two hour classes for my daily teaching schedule? How many people shall I teach? Where do classes take place?

2 hrs is average time; you can talk with host to schedule it, such as you can teach him 1 hr today and 3 hrs tomorrow depending on your tour plan. We define the teaching model as a one on one course; you can decide the place with the host by yourselves. We suggest you can go out with the host to practice some outdoor words.
