Perhaps you should try some spelling variations:
tinh luong » tinh huong, dinh luong, minh luong
luong quan » thong quan, duong qua
quan luat » quan luan, quan cua, quy luat
kiem soat » kiem toan
luat ke » luat ve, luan ket
quan va » quan vi, quan ha, luan va
quan li » quan ly, quan tri

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 luong quan luat ke soat ) OR ( tinh luong ((quan va) OR (quan li)) kiem soat ))~.
• Adding a wildcard symbol may retrieve word variants: (( tinh luong quan luat ke soat ) or ( tinh luong ((quan va) or (quan li)) kiem soat ))*.
