Perhaps you should try some spelling variations:
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hieu va » lieu va, hieu qua
va tham » van tham, va cham, va thanh
cua tre » cua te, cuu tre, cua triet
te cac » tu cac, ve cac, te cao
soc va » hoc va, doc va, goc va
loc va » hoc va
luc va » duc va, tuc va
vi cua » vai cua, di cua

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 cac ky lang xa hoi. hieu va tham ((soc va) OR (((loc va) OR (luc va)))) hanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ky lang xa hoi. hieu va tham ((soc va) or (((loc va) OR (luc va)))) hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te cac ky lang xa hoi. hieu va tham ((soc va) or (((loc va) OR (luc va)))) hanh vi cua tre*.
