Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
hien hanh » dieu hanh
hung cong » nhung cong, hung cuong, phung cong
tien anh » tieng anh, tien manh, dien anh
tran van » luan van
van hung » van dung, manh hung, van duong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap

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 ((tien anh) OR (hien hanh)) - thanh tran van hung cong dan than cao~.
• Adding a wildcard symbol may retrieve word variants: hoc ((tien anh) or (hien hanh)) - thanh tran van hung cong dan than cao*.
