tinh dung » trinh dung, tin dung, tinh quang
hieu soat » hieu suat, hieu hoat, hieu luat
kiem toan » ke toan, kiem tra
dung lan » dung luan, dung land, dung lam
van hieu » cao hieu
lan van » luan van, lang van, tan van

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( tinh dung lan van hieu soat ) or ( dinh ((cuong quan) OR (luong quan)) duong kiem toan ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh dung lan van hieu soat ) OR ( dinh ((cuong quan) OR (luong quan)) duong kiem toan )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh dung lan van hieu soat ) or ( dinh ((cuong quan) OR (luong quan)) duong kiem toan ))".
• Adding a wildcard symbol may retrieve word variants: (( tinh dung lan van hieu soat ) or ( dinh ((cuong quan) OR (luong quan)) duong kiem toan ))*.
