Perhaps you should try some spelling variations:
minh thong » minh thuong, minh tuong, minh thang
thong dung » thong cong, thong thuong
tinh huong » dinh huong, tinh quang, anh huong
huong luan » huong lan, cuong luan, huong loan
hieu soat » hieu suat, hieu hoat, hieu luat
kiem soat » kiem toan
dung cao » duong cao, dung cho, dung co
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: (( minh thong dung cao hieu soat ) OR ( tinh huong luan van kiem soat ))~.
• Adding a wildcard symbol may retrieve word variants: (( minh thong dung cao hieu soat ) or ( tinh huong luan van kiem soat ))*.
