Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
hang doanh » hanh doanh, nhung doanh, van doanh
doanh van » doan van, doanh va, doanh ban
van bang » van ban, van nang, von bang
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
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 sang)) - hang doanh van bang ((cong dan) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - hang doanh van bang ((cong dan) OR (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - hang doanh van bang ((cong dan) OR (cong tan)) toan cau*.
