Perhaps you should try some spelling variations:
tinh thuong » trinh thuong, tinh huong, tin thuong
dinh thuong » dinh huong, dinh duong, dinh cuong
quang tan » quang tuan, quang tran, quang toan
kiem toan » ke toan, kiem tra
van kiem » va kiem, van kien, van hieu
tan van » tran van, tang van, dang 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 thuong) OR (dinh thuong)) luan van kiem soat ) or ( tinh quang tan van kiem toan ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((tinh thuong) OR (dinh thuong)) luan van kiem soat ) OR ( tinh quang tan van kiem toan )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((tinh thuong) OR (dinh thuong)) luan van kiem soat ) or ( tinh quang tan van kiem toan ))".
• Adding a wildcard symbol may retrieve word variants: (( ((tinh thuong) OR (dinh thuong)) luan van kiem soat ) or ( tinh quang tan van kiem toan ))*.
