tinh voi » trinh voi, tinh doi, binh voi
nam thuc » nam thuoc, am thuc, nam thu
khac ty » khac thi

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: bui khac ty ang xa hoi. lieu va nam thuc va ((tinh vi) OR (tinh voi)) ((cua tu) OR (cua cu))~.
• Adding a wildcard symbol may retrieve word variants: bui khac ty ang xa hoi. lieu va nam thuc va ((tinh vi) or (tinh voi)) ((cua tu) or (cua cu))*.
