Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
doanh qua » doanh quan, doanh cua, doanh quang
dung cong » dung trong
danh qua » hanh qua, doanh quan, manh quan
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

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 tinh)) - doanh ((doanh qua) OR (danh qua)) dung cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - doanh ((doanh qua) OR (danh qua)) dung cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu tinh)) - doanh ((doanh qua) OR (danh qua)) dung cong dan toan cau*.
