Perhaps you should try some spelling variations:
thanh trung » thanh tung
nhieu tang » chieu sang, hieu lang, nhiet nang
trung cap » truong cao, trung tam
cap phong » chap phong, cac phong, cao phong
thanh cau » thanh chau, thanh mau, nhanh cau
cong ban » cong bang, cong tan, cong dan
cong san » cong tac

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