Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
thanh tinh » thanh binh, nhanh tinh, than kinh
cuong danh » cuon danh, huong dan, cuong linh
chat dong » chat long, chat cong, chat song
cong danh » cong dan, cong thanh, cong khanh

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 sach)) - thanh tinh chat dong ((cong danh) OR (cuong danh)) van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) OR (chieu sach)) - thanh tinh chat dong ((cong danh) or (cuong danh)) van ban~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) OR (chieu sach)) - thanh tinh chat dong ((cong danh) or (cuong danh)) van ban*.
