Perhaps you should try some spelling variations:
huong quan » luong quan, cuong quan, vuong quan
tinh dung » trinh dung, tin dung, tinh quang
hieu soat » hieu suat, hieu luat, kiem soat
hieu hoat » hieu hoa, thien hoat, hieu luat
kiem toan » ke toan, kiem tra
quan van » quan va, quan luan, quan doan
van kiem » va kiem, van kien, van hieu
luan » lan

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: (( tinh dung luan van ((hieu soat) OR (hieu hoat)) ) OR ( anh huong quan van kiem toan ))~.
• Adding a wildcard symbol may retrieve word variants: (( tinh dung luan van ((hieu soat) or (hieu hoat)) ) or ( anh huong quan van kiem toan ))*.
