Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
cham xuc » cam xuc, chat xuc, cham soc
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
van anh » van thanh, van minh
cua tre » cuu tre, cua triet, dua tren
y nang » ky nang, ly nang, v nang
cua te » cua tu
x hoi » xa hoi, o hoi, x ho
tuan » quan, tran, luan

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