Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
cong vang » cong lang, cong quang, cong ngang
chinh ca » chinh ta, chinh va, chinh tai
cong van » cong san, song van, cong tan
ca hang » cua hang, ca chang, va hang
van cau » van dau, van hau, van chat

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)) - hanh chinh ca hang ((cong van) OR (cong vang)) van cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - hanh chinh ca hang ((cong van) or (cong vang)) van cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sang)) - hanh chinh ca hang ((cong van) or (cong vang)) van cau*.
