Perhaps you should try some spelling variations:
quang luan » quan luan, quang tuan, quang uan
dung lquan » dung luan, dung quan, dung quang
kiem soat » kiem toan
lquan vu » quan vi, luan va, quan su
van kiem » va kiem, van kien, van hieu
le doan » le dan, ly doanh, le hoang
vu le » va le

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: (( tin dung lquan vu le doan ) OR ( tinh quang luan van kiem soat ))~.
• Adding a wildcard symbol may retrieve word variants: (( tin dung lquan vu le doan ) or ( tinh quang luan van kiem soat ))*.
