Perhaps you should try some spelling variations:
luong quan » duong qua
tinh thong » tinh thuong, trinh thong, tinh khong
hieu soat » hieu hoat, hieu luat, kiem soat
hieu suat » hieu luat, hieu qua
kiem toan » ke toan, kiem tra
quan van » luan van, quan luan, quan doan
quan va » quan vi, quan ha, luan va
va kiem » van kien
tien » tieng, bien, vien

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

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