Perhaps you should try some spelling variations:
chieu sang » chieu sach, hieu lang, nhieu tang
chieu xanh » chieu sach, chieu tinh, hieu manh
canh manh » lanh manh, canh tranh, cach mang
cua trong » cua truong, cua trung, qua trong
manh cua » doanh cua, ban cua
cong dan » cong tan, huong dan, cong dong
cong san » cong tac

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