Perhaps you should try some spelling variations:
trinh thuong » trinh phuong, trinh huong, trinh truong
thuong luan » thuong lan, thong luan, truong luan
minh thong » minh thuong, minh tuong, minh thang
thong dung » thong cong, thong thuong
hieu soat » hieu hoat, hieu luat, kiem soat
hieu suat » hieu luat, hieu qua
kiem toan » ke toan, kiem tra
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 va ((hieu soat) OR (hieu suat)) ) OR ( trinh thuong luan van kiem toan ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( minh thong dung va ((hieu soat) OR (hieu suat)) ) or ( trinh thuong luan van kiem toan ))~".
• Adding a wildcard symbol may retrieve word variants: (( minh thong dung va ((hieu soat) OR (hieu suat)) ) or ( trinh thuong luan van kiem toan ))*.
