Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
cham xuc » cam xuc, chat xuc, cham soc
hanh dai » hanh tai, hanh dao, vanh dai
lang xa » lang ha, dang xay, lang van
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
su xac » pu xac, su cac
o lang » hoa lang, hoi lang
xuc va » duc va, tuc va, luc va
xac o » sac o, cac o

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 xac o lang xa hoi. ((hieu van) OR (hieu qua)) cham xuc va hanh dai cua tre~.
• Adding a wildcard symbol may retrieve word variants: su xac o lang xa hoi. ((hieu van) or (hieu qua)) cham xuc va hanh dai cua tre*.
