Perhaps you should try some spelling variations:
tinh luong » tinh huong, dinh luong, minh luong
dang quang » dung quang, nang quan, dang hung
luong quan » thong quan, duong qua
lieu luat » hieu luat, lieu thuat, hieu suat
kiem soat » kiem toan
dung cua » dung luan, dung cho
so lieu » so dieu
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( tinh ((dung cua) OR (dang quang)) so lieu luat ) OR ( tinh luong quan va kiem soat ))~.
• Adding a wildcard symbol may retrieve word variants: (( tinh ((dung cua) or (dang quang)) so lieu luat ) or ( tinh luong quan va kiem soat ))*.
