Perhaps you should try some spelling variations:
trinh quan » tinh quang, trinh luat, trinh han
tinh dung » trinh dung, tin dung, tinh quang
hieu luat » hieu qua
kiem toan » ke toan, kiem tra
van hieu » cao hieu
quan sat » quan ha, quan tai, luan san
van kiem » va kiem, van kien, van hien
sat van » sat va, hat van, hoat van
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 luat ) OR ( trinh quan sat van kiem toan ))~.
• Adding a wildcard symbol may retrieve word variants: (( tinh dung luan van hieu luat ) or ( trinh quan sat van kiem toan ))*.
