Perhaps you should try some spelling variations:
hieu sau » hieu suat, tieu su, hieu va
toc sach » hoc sach, doc sach, thuoc sach
cham xuc » cam xuc, chat xuc, cham soc
hieu su » tieu su, hieu so, hieu suat
van anh » van thanh, van minh
lai cua » dai cua, hai cua, lai chau
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
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 ho. ((hieu su) OR (hieu sau)) cham xuc ((van anh) OR (tuan anh)) lai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach y nang x ho. ((hieu su) or (hieu sau)) cham xuc ((van anh) OR (tuan anh)) lai cua tre~".
• Adding a wildcard symbol may retrieve word variants: toc sach y nang x ho. ((hieu su) or (hieu sau)) cham xuc ((van anh) OR (tuan anh)) lai cua tre*.
