Perhaps you should try some spelling variations:
thuoc sach » hoc sach, nuoc sach, thuat sach
hanh tai » thanh tai, hang tai, han tai
hanh dai » hanh dao, vanh dai, thanh dat
te sach » toc sach
cac xuc » cam xuc, cac nuoc, chat xuc
cua tre » cua te, cuu tre, cua triet
hieu ve » hieu va, hieu van
dang xa » dang xay, lang xa, dang ha
ky dang » ky nang, ky danh
xuc va » duc va, tuc va, luc va
ve cac » va cac, vien cac

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 (thuoc sach)) ky dang xa hoi. hieu ve cac xuc va ((hanh dai) OR (hanh tai)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (thuoc sach)) ky dang xa hoi. hieu ve cac xuc va ((hanh dai) OR (hanh tai)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (thuoc sach)) ky dang xa hoi. hieu ve cac xuc va ((hanh dai) OR (hanh tai)) cua tre*.
