Perhaps you should try some spelling variations:
toc sach » doc sach, thuoc sach, nuoc 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
hoc sach » hoc sinh, hoc cac, hoc anh
nang xa » nang x, lang xa, nang ma
danh va » doanh va, anh va, dan va
hanh va » hang va, hanh vi
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc 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: ((toc sach) OR (hoc sach)) y nang xa hoi. hieu van cham xuc va ((danh va) OR (hanh va)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) OR (hoc sach)) y nang xa hoi. hieu van cham xuc va ((danh va) or (hanh va)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((toc sach) OR (hoc sach)) y nang xa hoi. hieu van cham xuc va ((danh va) or (hanh va)) cua tre*.
