Perhaps you should try some spelling variations:
thuoc sach » hoc sach, nuoc sach, thuat sach
cham xuc » cam xuc, chat xuc, cham soc
vanh tai » van tai, hanh tai, vanh dai
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
xuc van » duc van, luc van, vuc van
anh tai » hanh tai, anh thai, xanh tai
cua tre » cua te, cuu tre, cua triet
y nang » ly nang, v nang, may nang
x hoi » xa hoi, o hoi, x ho

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: thuoc sach ((y nang) OR (ky nang)) x hoi. hieu vu cham xuc van ((anh tai) OR (vanh tai)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ((y nang) or (ky nang)) x hoi. hieu vu cham xuc van ((anh tai) OR (vanh tai)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: thuoc sach ((y nang) or (ky nang)) x hoi. hieu vu cham xuc van ((anh tai) OR (vanh tai)) cua tre*.
