Perhaps you should try some spelling variations:
thanh trung » thanh tung
trung thanh » truong thanh
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
thanh hoa » thanh pho
thanh cau » thanh chau, thanh mau, nhanh cau
cong van » cong vang, song van, cong tan
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: theo ((chieu xanh) OR (chieu sang)) - thanh trung thanh hoa ((cong van) OR (cong san)) thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - thanh trung thanh hoa ((cong van) or (cong san)) thanh cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sang)) - thanh trung thanh hoa ((cong van) or (cong san)) thanh cau*.
