Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
van cham » van chat, van tham, va cham
hieu van » hieu va, thien van, lieu va
cham xuc » cam xuc, chat xuc, cham soc
ky danh » ky anh, ky dang
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
va don » va dong, va doc, la don
va do » va dao, va doc, va co

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