Perhaps you should try some spelling variations:
cuon sach » duong sach, cuoc cach, co sach
thanh vai » thanh hai, thanh van, thanh tai
hoc sach » hoc sinh, hoc cac, hoc anh
va thanh » gia thanh, ban thanh, va tinh
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
va nang » van nang, da nang, cam nang
tuc va » thuc va, truc va, tuc xa
va cam » va cham, va cao, 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 (cuon sach)) va nang xa hoi. lieu ((va cam) OR (va cac)) tuc va thanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc sach) or (cuon sach)) va nang xa hoi. lieu ((va cam) OR (va cac)) tuc va thanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((hoc sach) or (cuon sach)) va nang xa hoi. lieu ((va cam) OR (va cac)) tuc va thanh vai cua tre*.
