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
trung va » truong va, trang va, trung ha
cong ban » cong bang, cong tan, cong dan
cong san » cong tac
hang cau » hang dau, hang ca, nhung cau

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 va nhung ((cong ban) OR (cong san)) hang cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - thanh trung va nhung ((cong ban) or (cong san)) hang cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - thanh trung va nhung ((cong ban) or (cong san)) hang cau*.
