Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
hanh ban » thanh ban, hang ban, hanh han
hanh san » thanh san, khach san, thanh son
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: theo ((chieu xanh) OR (trieu tinh)) - ((hanh ban) OR (hanh san)) va nhung cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (trieu tinh)) - ((hanh ban) OR (hanh san)) va nhung cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (trieu tinh)) - ((hanh ban) OR (hanh san)) va nhung cong dan toan cau*.
