tin luong » tien luong, tin huong, tin tuong
hieu suat » hieu luat, hieu qua
kiem toan » ke toan, kiem tra
quan van » luan van, quan luan, quan doan
van hieu » cao hieu
quan va » quan vi, quan ha, luan va

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

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