Perhaps you should try some spelling variations:
doanh doanh » toan doanh, doanh hoan, doanh thanh
theo chieu » theo tieu, ho chieu, theo chu
doanh hanh » doanh thanh, doanh anh, doanh nhan
dung cong » dung trong
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban
cho chu » cho thue
va dung » van dung, va duong, vat dung

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) OR (cho chu)) xanh - ((doanh hanh) OR (doanh doanh)) va dung cong dan toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (cho chu)) xanh - ((doanh hanh) OR (doanh doanh)) va dung cong dan toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (cho chu)) xanh - ((doanh hanh) OR (doanh doanh)) va dung cong dan toan ban*.
