Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
nhung cong » dung cong, thong cong, hang cong
tung tuan » trung tuan, quang tuan, trang tuan
hung tuan » hung tran, quang tuan, trung tuan
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 sach)) - thanh ((tung tuan) OR (hung tuan)) nhung cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sach)) - thanh ((tung tuan) OR (hung tuan)) nhung cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sach)) - thanh ((tung tuan) OR (hung tuan)) nhung cong dan toan cau*.
