Perhaps you should try some spelling variations:
chieu trach » chiu trach, chien tranh, chiet tach
theo chieu » theo tieu, ho chieu, theo chu
vat cuong » van cuong, vat duong, viet cuong
danh toan » manh toan, anh toan, dang toan
anh manh » lanh manh, anh anh, ranh mach
anh danh » anh anh, anh dang, anh dinh
dan toan » van toan, dan than, manh toan

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