Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hanh mang » nhanh mang, hanh trang, nhanh lang
cua nhung » va nhung
doi chiu » doi chieu, doi chi, hoi chiu
mang cua » manh cua, dung cua, ban cua
dan than » dan chan, ban than, dan toan
van than » van thanh, van thang, van tuan

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: doi chiu trach - hanh mang cua nhung cong ((dan than) OR (van than)) ban~.
• Adding a wildcard symbol may retrieve word variants: doi chiu trach - hanh mang cua nhung cong ((dan than) or (van than)) ban*.
