Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
hien hanh » dieu hanh
van nhung » van nhuong, va nhung, van hung
hien anh » thien anh, dien anh, tien anh
tran van » luan van
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
chan cao » chan cho, chat cao, chay cao

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 ((hien anh) OR (hien hanh)) - thanh tran van nhung ((cong dan) OR (cong san)) chan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien anh) OR (hien hanh)) - thanh tran van nhung ((cong dan) or (cong san)) chan cao~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien anh) OR (hien hanh)) - thanh tran van nhung ((cong dan) or (cong san)) chan cao*.
