Perhaps you should try some spelling variations:
hanh lai » hanh lam, hanh tai, thanh lap
chat xuc » chat huu, cam xuc, chao xu
su sach » so sach, vu sach
lai cua » dai cua, hai cua, lai chau
va hanh » van hanh, va thanh, va danh
cac xuc » cam xuc, cac nuoc, cac cuoc
hieu va » lieu va, hieu qua
cua tre » cua te, cuu tre, cua triet
y sang » _ sang, duy sang
ma hoi » mai hoi, ma hoa, me hoi

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