Perhaps you should try some spelling variations:
thuong cong » thong cong, thuong con, thuong dong
thanh trung » thanh tung
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
tam thuong » tai thuong, tam huong, pham thuong
san thanh » van thanh, son thanh, dan thanh
ban thanh » ban hanh, ban hang

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 xanh) OR (chieu sang)) - thanh trung tam thuong cong ((san thanh) OR (ban thanh)) mau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu sang)) - thanh trung tam thuong cong ((san thanh) OR (ban thanh)) mau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu sang)) - thanh trung tam thuong cong ((san thanh) OR (ban thanh)) mau*.
