If you're talking about Chinese language course at Yunnan Uni's international college then classes are 8:30 - 12:00 or 10:20 - 14:40 (with one hour lunch break). There are three subjects: speaking, listening and comprehensive. You have to choose comprehensive, other two are optional. One semester costs 6000 rmb, starts 1.09 ends 10.01, then I think 3.03 - 10.07.
Ah, try calling them, but finding someone who speaks English there is really difficult.
