Perhaps you should try some spelling variations:
thanh trung » thanh tung
theo chieu » theo tieu, ho chieu, theo chu
doi chieu » doc hieu, doi chi, ho chieu
va duong » van duong, va tuong, va huong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cao » toan cao, thai cao, than cap
va dung » van dung, vat dung, va ung

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: ((doi chieu) OR (theo chieu)) xanh - thanh trung ((va dung) OR (va duong)) cong dan than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) or (theo chieu)) xanh - thanh trung ((va dung) OR (va duong)) cong dan than cao~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) or (theo chieu)) xanh - thanh trung ((va dung) OR (va duong)) cong dan than cao*.
