Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
cong doan » cong hoan, dong doanh, cong san
tranh ha » thanh ha, trang ha, trinh ha
cong dan » cong san, cong tan, huong dan
phan cac » nhan cach, phan dau, phan lap
ha dong » hoat dong, van dong

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