Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
chat xuc » chat huu, cam xuc, chao xu
cham xuc » cam xuc, cham soc, pham duc
hieu ve » hieu van
hieu va » lieu va, hieu qua
van anh » van thanh, tuan anh, van minh
anh lai » anh bai, anh tai, gianh lai
lai cua » dai cua, hai cua, lai chau
cua tre » cua te, cuu tre, cua triet
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 y nang x hoi. ((hieu ve) OR (hieu va)) ((cham xuc) OR (chat xuc)) van anh lai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y nang x hoi. ((hieu ve) or (hieu va)) ((cham xuc) OR (chat xuc)) van anh lai cua tre~".
• Adding a wildcard symbol may retrieve word variants: toc sach y nang x hoi. ((hieu ve) or (hieu va)) ((cham xuc) OR (chat xuc)) van anh lai cua tre*.
