nang xa » nang x, lang xa, nang ma
hieu ve » hieu van
hieu va » lieu va, hieu qua
sach ty » sach y, sach tu, sach thu
tuc va » thuc va, truc va, tuc xa
vi cua » vai cua, di cua
xac va » tac va, ac va, bac va

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: tu sach ty nang xa hoi. ((hieu ve) OR (hieu va)) cam ((xac va) OR (tuc va)) hanh vi cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang xa hoi. ((hieu ve) or (hieu va)) cam ((xac va) or (tuc va)) hanh vi cua te*.
