Perhaps you should try some spelling variations:
chieu trach » chiu trach, chien tranh, chiet tach
theo chieu » theo tieu, ho chieu, theo chu
trinh mach » tinh mach, trinh lich, trinh minh
anh dinh » hanh dinh, lanh dinh, anh kinh
ban cong » bang cong, van cong, phan cong
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan ban » van ban

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 - ((trinh mach) OR (anh dinh)) cua ban cong dan toan ban~.
• Adding a wildcard symbol may retrieve word variants: theo chieu trach - ((trinh mach) or (anh dinh)) cua ban cong dan toan ban*.
