Perhaps you should try some spelling variations:

nhung cong » dung cong, thong cong, hang cong
cua nhung » va nhung
anh tang » anh bang, anh nang, anh sang
anh dang » anh dong, anh dung, anh bang
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cap » khan cap, thanh lap, thanh cac

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 xanh) OR (chieu sach)) - ((anh tang) OR (anh dang)) cua nhung cong dan than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - ((anh tang) or (anh dang)) cua nhung cong dan than cap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - ((anh tang) or (anh dang)) cua nhung cong dan than cap*.
