Perhaps you should try some spelling variations:
chieu xanh » chieu sang, chieu tinh, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
tranh cua » doanh cua, manh cua
hang cong » hang nong, bang cong, thanh cong
dang cong » dung cong
tan toan » tan tran, tap toan, van toan
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: doi ((chieu xanh) OR (chieu sach)) - canh tranh cua ((hang cong) OR (dang cong)) tan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu sach)) - canh tranh cua ((hang cong) OR (dang cong)) tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu xanh) or (chieu sach)) - canh tranh cua ((hang cong) OR (dang cong)) tan toan cao*.
