Perhaps you should try some spelling variations:
thuoc sach » hoc sach, nuoc sach, thuat sach
van thanh » ban thanh, van tuan
toc sach » hoc sach, doc sach, nuoc sach
cham xuc » cam xuc, chat xuc, cham soc
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
xuc van » duc van, luc van, vuc van
lai cua » hai cua, lai chau, thai cua
y nang » ky nang, ly nang, v 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: ((toc sach) OR (thuoc sach)) y nang x hoi. hieu ve cham xuc van thanh ((lai cua) OR (dai cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc sach) OR (thuoc sach)) y nang x hoi. hieu ve cham xuc van thanh ((lai cua) or (dai cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: ((toc sach) OR (thuoc sach)) y nang x hoi. hieu ve cham xuc van thanh ((lai cua) or (dai cua)) tre*.
