Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
theo chiet » theo chieu, thep thiet
thep viet » phap viet, te viet, thai viet
cua nhung » va nhung
hanh ban » thanh ban, hang ban, hanh san
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than tap » toan tap, han tap, phan tap
ban cua » ban quan

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 chiet) OR (thep viet)) tach - hanh ban cua nhung cong dan than tap~.
• Adding a wildcard symbol may retrieve word variants: ((theo chiet) or (thep viet)) tach - hanh ban cua nhung cong dan than tap*.
