nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
danh ve » dinh ve, hanh ve, anh ve
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
ve cam » ve cham, ve cac, va cam

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: te sac ky nang xa hoi. hieu ve cam ((duc va) OR (thuc day)) ((danh ve) OR (dinh van)) su triet.
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. hieu ve cam ((duc va) or (thuc day)) ((danh ve) or (dinh van)) su triet*.
