Perhaps you should try some spelling variations:
trinh huong » trinh phuong, tinh huong, trinh duong
minh tuong » minh tuan, minh quang
tuong dung » tuong duong, thuong dung, thong dung
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 tuong dung cao hieu soat ) OR ( trinh huong luan van kiem soat ))~.
• Adding a wildcard symbol may retrieve word variants: (( minh tuong dung cao hieu soat ) or ( trinh huong luan van kiem soat ))*.
