Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh dung » thanh dung, anh dung, hanh dong
cho hang » cho thanh, cho phan, cho cong
thi hang » thi hanh, thi nang, thi hong
dan toan » van toan, dan than, manh toan
van tai » von tai, van tuan

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 - hanh dung ((cho hang) OR (thi hang)) cung ((dan toan) OR (van tai)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu xanh - hanh dung ((cho hang) OR (thi hang)) cung ((dan toan) or (van tai)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu xanh - hanh dung ((cho hang) OR (thi hang)) cung ((dan toan) or (van tai)) cau*.
