Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
hieu van » hieu va, thien van, lieu va
van cham » van chat, van tham, va cham
cham xuc » cam xuc, chat xuc, cham soc
va thanh » gia thanh, ban thanh, va tinh
va hanh » van hanh, ban hanh, dao hanh
vai cua » dai cua, hai cua, lai cua
va danh » va dinh, va dan, dia danh
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
y nang » ky nang, ly nang, v nang

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: toc sach y nang xa hoi. hieu van cham xuc ((va danh) OR (((va hanh) OR (va thanh)))) vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y nang xa hoi. hieu van cham xuc ((va danh) or (((va hanh) OR (va thanh)))) vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: toc sach y nang xa hoi. hieu van cham xuc ((va danh) or (((va hanh) OR (va thanh)))) vai cua tre*.
