Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
van chat » cao chat
chat xuc » chat huu, cam xuc, chao xu
sach ty » sach tu, sach thu, xach tay
van dai » vanh dai, van dao, van hai
cua tre » cua te, cuu tre, cua triet
nang o » nang co, nang ho, nang ro
xuc va » duc va, tuc va, luc va
o hoi » co hoi, o hoc, o hai

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: thu ((sach y) OR (sach ty)) nang o hoi. hieu van chat xuc va van dai cua tre~.
• Adding a wildcard symbol may retrieve word variants: thu ((sach y) or (sach ty)) nang o hoi. hieu van chat xuc va van dai cua tre*.
