Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
chau tinh » cuu tinh, ha tinh, cua tinh
thanh ban » thanh san, thanh van, thanh bac
dung cong » dung trong
cong dan » cong san, cong tan, huong dan
toan ban » van ban
va dung » van dung, va duong, vat dung

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 (chau tinh)) - thanh ban va dung cong dan ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chau tinh)) - thanh ban va dung cong dan ((toan tap) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chau tinh)) - thanh ban va dung cong dan ((toan tap) OR (toan ban))*.
