Perhaps you should try some spelling variations:
nuoc sach » nguoi sach, cuoc cach, cuon sach
hoc sach » hoc sinh, hoc cac, hoc anh
hanh vai » hanh vi, hanh va, hanh tai
van hanh » van thanh, ban hanh, van anh
dang cay » dang xay, dang ca, dang cac
cay phoi » cap phoi, tay hoi, cay cho
vai cua » dai cua, hai cua, lai cua
xuc van » duc van, luc van, vuc van
cua tre » cua te, cuu tre, cua triet
ky dang » ky nang, ky danh
va cao » va cac, va co, va dao
va cam » va cham, va cac, va cai

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: ((hoc sach) OR (nuoc sach)) ky dang cay phoi. hieu ((va cam) OR (va cao)) xuc van hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sach) or (nuoc sach)) ky dang cay phoi. hieu ((va cam) OR (va cao)) xuc van hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((hoc sach) or (nuoc sach)) ky dang cay phoi. hieu ((va cam) OR (va cao)) xuc van hanh vai cua tre*.
