Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
dang hai » dang khai, hang hai, dung hai
van dang » van dong, van dung, van nang
chat xuc » chat huu, cam xuc, chao xu
hieu ve » hieu va, hieu van
hai cua » thai cua, dai cua, hoi cua
xuc van » duc van, luc van, vuc van
ve chat » va chat, van chat
cua tre » cua te, cuu tre, cua triet
v nang » va nang, vu nang, van nang
y nang » ky nang, ly nang, may 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: ((te sach) OR (toc sach)) ((y nang) OR (v nang)) xa hoi. hieu ve chat xuc van dang hai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) ((y nang) or (v nang)) xa hoi. hieu ve chat xuc van dang hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) ((y nang) or (v nang)) xa hoi. hieu ve chat xuc van dang hai cua tre*.
