Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
van lam » van nam
lam xuc » cam xuc, lam duoc
dinh vi » dinh ve, dinh viet, dinh tri
cua tre » cua te, cuu tre, cua triet
te sac » te sach, te cac, te san
te cao » te bao
xuc va » duc va, tuc va, luc 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: ((te sac) OR (te cao)) ky lang xa hoi. hieu van lam xuc va ((dinh van) OR (dinh vi)) cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (te cao)) ky lang xa hoi. hieu van lam xuc va ((dinh van) or (dinh vi)) cua tre*.
