Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
tien thanh » tien thinh, tran thanh, den thanh
cua nhung » va nhung
anh hang » anh hoang, anh hung, anh bang
hang cua » mang cua, hang ca, huong cua
cong dan » cong san, cong tan, huong dan
chan ban » can ban, chan nan, chan doan
chat ban » nhat ban, chat ran, cua 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: hoc ((tien thanh) OR (tieng anh)) - anh hang cua nhung cong dan ((chan ban) OR (chat ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((tien thanh) or (tieng anh)) - anh hang cua nhung cong dan ((chan ban) OR (chat ban))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((tien thanh) or (tieng anh)) - anh hang cua nhung cong dan ((chan ban) OR (chat ban))*.
