Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
chiet tach » chieu sach
canh manh » lanh manh, canh tranh, cach mang
manh cua » doanh cua, ban cua
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
phan cau » phan dau, phan cac, phan tu

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 sang) OR (chiet tach)) - canh manh cua cong ((cong dan) OR (cong san)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chiet tach)) - canh manh cua cong ((cong dan) OR (cong san)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (chiet tach)) - canh manh cua cong ((cong dan) OR (cong san)) phan cau*.
