Perhaps you should try some spelling variations:
tinh luong » tinh huong, minh luong, tinh cuong
dinh luong » dinh duong, dinh huong, dinh cuong
tinh nang » trinh nang, tin nang, tich nang
nang quan » ban quan, nang suat
hieu soat » hieu suat, hieu hoat, hieu luat
kiem toan » ke toan, kiem tra
quan ban » quang ban, qua ban, luan ban
ban hieu » van hieu, gian hieu, phan hieu
quan van » luan van, quan va, quan luan
van kiem » va kiem, van kien, van hieu

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 nang quan ban hieu soat ) OR ( ((tinh luong) OR (dinh luong)) quan van kiem toan ))~.
• Adding a wildcard symbol may retrieve word variants: (( tinh nang quan ban hieu soat ) or ( ((tinh luong) or (dinh luong)) quan van kiem toan ))*.
