Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
tranh cua » doanh cua, manh cua
cong cong » cong dong, trong cong, dung cong
cong dan » cong san, cong tan, huong dan
phan cau » phan dau, phan tu, phan lap
phan cac » nhan cach, phan dau, phan lap

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