Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
cuong cong » cong cong, luong cong, duong cong
hieu manh » chieu xanh, hieu nganh, hien hanh
van cuong » van chuong, van duong, van cong
dan thanh » dang thanh, danh thanh, ban thanh
thanh lap » thanh san, phan lap, thanh hai
tran van » luan van
cong dan » cong san, cong tan, huong dan

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 ((hieu manh) OR (dieu hanh)) - thanh tran van cuong cong dan thanh lap~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hieu manh) or (dieu hanh)) - thanh tran van cuong cong dan thanh lap*.
