Perhaps you should try some spelling variations:
thieu xanh » chieu xanh, thien danh
thanh tran » thanh trang, thanh toan, thanh tra
hieu manh » chieu xanh, hieu nganh, dieu hanh
thien anh » thien danh, tien anh, thien thanh
dung cong » dung trong
tran van » luan van
van dung » van dong, xay dung, tin dung
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 ((((thieu xanh) OR (hieu manh))) OR (thien anh)) - thanh tran van dung cong dan than cao~.
• Adding a wildcard symbol may retrieve word variants: hoc ((((thieu xanh) or (hieu manh))) or (thien anh)) - thanh tran van dung cong dan than cao*.
