Perhaps you should try some spelling variations:
thien van » thi van
hieu van » hieu va, lieu va, hieu ve
cham xuc » cam xuc, chat xuc, cham soc
nang xa » nang x, lang xa, nang ma
xuc ban » duc ban, cuc ban, quoc ban
cuu tre » cua tre, cau tren, cau treo
tu cai » tu cac, tu can, tu bai
cai ky » cao ky, cac ky, cam ky
anh vi » hanh vi, anh ve, anh vu
anh va » hanh 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 cai ky nang xa hoi. ((hieu van) OR (thien van)) cham xuc ban ((anh vi) OR (anh va)) cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cai ky nang xa hoi. ((hieu van) or (thien van)) cham xuc ban ((anh vi) OR (anh va)) cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu cai ky nang xa hoi. ((hieu van) or (thien van)) cham xuc ban ((anh vi) OR (anh va)) cuu tre*.
