Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, te sach
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
van anh » van thanh, tuan anh, van minh
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
y sang » _ sang, duy sang
ma hoi » mai hoi, ma hoa, me hoi
va cam » va cham, va cac, va cao

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