Perhaps you should try some spelling variations:
minh luong » dinh luong, minh tuong, minh cuong
luong quan » thong quan, duong qua
tinh dung » trinh dung, tin dung, tinh quang
dung chan » dung nhan, dung phan, dung chat
hieu soat » hieu suat, hieu hoat, hieu so
hieu luat » hieu qua
kiem soat » kiem toan
quan va » quan vi, quan ha, luan va
va kiem » van kien

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 chan doan ((hieu soat) OR (hieu luat)) ) or ( minh luong quan va kiem soat ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh dung chan doan ((hieu soat) OR (hieu luat)) ) OR ( minh luong quan va kiem soat ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tinh dung chan doan ((hieu soat) OR (hieu luat)) ) or ( minh luong quan va kiem soat ))*".
