Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
xuc va » tuc va, luc va, xac va
vi cua » vai cua, di cua
cua tu » cua tuc, cua su, cua cu

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 sac ky nang xa hoi. ((hieu ve) OR (hieu van)) cam ((xuc va) OR (duc va)) hanh vi cua tu~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. ((hieu ve) or (hieu van)) cam ((xuc va) or (duc va)) hanh vi cua tu*.
