Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
dai luong » dai cuong, dai duong, hai duong
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than cap » khan cap, thanh lap, thanh cac

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: ho ((chieu xanh) OR (chieu sach)) - thanh trung ((dai luong) OR (do luong)) cong tan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - thanh trung ((dai luong) OR (do luong)) cong tan than cap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - thanh trung ((dai luong) OR (do luong)) cong tan than cap*.
