Schools generally have classrooms. I don't know how big you need and how many people you can take classes. You can ask Xiamen University. I know that the lecture hall of the Institute of Chemistry and Chemical Engineering can be rented. The telephone number of the office is 2 186405. At the same time, the lecture hall is relatively large, and it should be no problem for 2-300 people to attend classes. In addition, public classrooms of other departments should also be rented out at some time. For details, please check with Xiamen University School of Finance and Economics and other departments.

Otherwise, find a language training institution, such as Buckingham in Langner and other English teaching units, and make sure they have teachers. If you want to pay for the classroom, of course they will be happy.
