Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
cua dung » cua dang, cua dong, cua rung
qua dung » quang dung, su dung, qua song
cong san » cong tac
san can » san van, ban can, san chang
can cau » van cau, ban cau, ca cau

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: ho ((chieu xanh) OR (chieu sach)) - canh tranh ((cua dung) OR (qua dung)) cong san can cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - canh tranh ((cua dung) or (qua dung)) cong san can cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - canh tranh ((cua dung) or (qua dung)) cong san can cau*.
