Dalian has a French department, that is, Dawai and Liaoshi are only available for college students.
Tcf and so on all go to the imperial city to take an examination.
I am a Dalian student in the French Department.
If you still don't know what to do, you can go to the French Union for consultation (just near the university ~ of course, the old campus)
The lottery is to decide whether to take tef or tcf at the examination place.
There is a big difference between the two, one is the plus point system and the other is the minus point system.
