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

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 y sang ((ma hoi) OR (xa hoi)). hieu van cam xuc va hanh lai cua tre~.
• Adding a wildcard symbol may retrieve word variants: su sach y sang ((ma hoi) or (xa hoi)). hieu van cam xuc va hanh lai cua tre*.
