Perhaps you should try some spelling variations:
chieu trach » chiu trach, chien tranh, chiet tach
theo chieu » theo tieu, ho chieu, theo chu
hanh trinh » canh tranh, hanh chinh
danh toan » anh toan, dan toan, dang toan
manh toan » thanh toan, anh tuan, tinh toan
anh danh » anh anh, anh dang, anh dinh
van cong » van dong, van phong, phan cong
cua van » cua ban, cua vat, cua dan

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 trach - ((hanh trinh) OR (anh danh)) cua van cong ((danh toan) OR (manh toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu trach - ((hanh trinh) or (anh danh)) cua van cong ((danh toan) OR (manh toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu trach - ((hanh trinh) or (anh danh)) cua van cong ((danh toan) OR (manh toan)) cau*.
