Perhaps you should try some spelling variations:
chien tranh » hien trang
theo chien » theo chieu, thien chien, thi chien
lanh manh » lanh tranh, lan anh, van manh
van phong » van dong, hai phong
danh toan » manh toan, anh toan, dan toan
anh dong » anh huong, anh son
van cong » van dong, phan cong, van duong
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: theo chien tranh - ((lanh manh) OR (anh dong)) cua ((van cong) OR (van phong)) danh toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chien tranh - ((lanh manh) or (anh dong)) cua ((van cong) OR (van phong)) danh toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo chien tranh - ((lanh manh) or (anh dong)) cua ((van cong) OR (van phong)) danh toan cau*.
