Perhaps you should try some spelling variations:
hanh lai » hanh lam, hanh tai, thanh lap
hieu ve » hieu va, hieu van
lai cua » dai cua, hai cua, lai chau
va hanh » van hanh, va thanh, va danh
cac xuc » cam xuc, cac nuoc, chat xuc
su sach » so sach
vu sach » vu bach, vu khach
cua tre » cua te, cuu tre, cua triet
ma hoi » mai hoi, ma hoa, me hoi
ve cac » va cac, vien cac
xuc va » duc va, tuc va, luc va
y sang » _ sang, duy sang

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: ((su sach) OR (vu sach)) y sang ((ma hoi) OR (xa hoi)). hieu ve cac xuc va hanh lai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) y sang ((ma hoi) or (xa hoi)). hieu ve cac xuc va hanh lai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) y sang ((ma hoi) or (xa hoi)). hieu ve cac xuc va hanh lai cua tre*.
