Perhaps you should try some spelling variations:
nhung tri » nhung bai, dung tri, nhung bi
thi quyet » thi tuyet, toi quyet, theo quyet
tri quan » trinh quan, hai quan, mai quan
quan van » luan van, quan va, quan luan
hoi dong » hop dong, hoat dong, ha dong
dong hoc » dong co, dong luc
hoc mo » hoc moi, hoc mot, hoc mon

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( nhung tri quan van. hoi dong hoc mo ) OR ( phung thi quyet van. van dong hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (( nhung tri quan van. hoi dong hoc mo ) or ( phung thi quyet van. van dong hoc mo ))*.
