Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
van cham » van chat, van tham, va cham
cham xuc » cam xuc, chat xuc, cham soc
te sach » toc sach
su dang » su dung
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
cua tre » cua te, cuu tre, cua triet
v nang » va nang, vu nang, van nang
xuc va » duc va, tuc va, luc 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 sach ((v nang) OR (su dang)) xa hoi. hieu van cham xuc va danh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sach ((v nang) or (su dang)) xa hoi. hieu van cham xuc va danh vi cua tre*.
