ve triet » va trien, su triet
ky tang » ky nang, ky dang, kho tang

dinh ve » dinh ket, dinh van
te san » te ban, ke san, tu san
san ky » sang ky, van ky, dan ky
va cam » va cham, va cac, va cao
tuc va » thuc va, truc va, tuc xa

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 san ky tang xa hoi. hieu va cam tuc va ((((danh viet) OR (dinh ve))) OR (anh viet)) ve triet.
• Adding a wildcard symbol may retrieve word variants: te san ky tang xa hoi. hieu va cam tuc va ((((danh viet) or (dinh ve))) or (anh viet)) ve triet*.
