Perhaps you should try some spelling variations:
nhung chong » nhung cong, nhung phong, nhung phuong
phung cong » nhung cong, phong cong, dung cong
hoc quyet » hoc quyen, hoc thuyet, hoc quy
hanh luan » khanh luan, hang luan, hanh luat
manh toan » thanh toan, anh tuan, tinh toan
dan chan » dan gian, dan ca, van chat

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: hoc quyet thanh - hanh luan van ((phung cong) OR (nhung chong)) ((manh toan) OR (dan chan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc quyet thanh - hanh luan van ((phung cong) OR (nhung chong)) ((manh toan) or (dan chan)) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc quyet thanh - hanh luan van ((phung cong) OR (nhung chong)) ((manh toan) or (dan chan)) cau*.
