Perhaps you should try some spelling variations:
thanh lai » thanh hai, thanh lap, thanh loi
hieu ve » hieu va, hieu van
xuc ban » duc ban, quoc ban, xuat ban
cuc ban » cua ban, cac ban, cuu ban
lai cua » dai cua, hai cua, lai chau
cua tre » cua te, cuu tre, cua triet
te sac » te sach, te cac, te san
sac ky » cac ky, sai ky
nang o » nang co, nang ho, nang ro
ve cam » ve cham, ve cac, va cam
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: te sac ky nang o hoi. hieu ve cam ((xuc ban) OR (cuc ban)) thanh lai cua tre~.
• Adding a wildcard symbol may retrieve word variants: te sac ky nang o hoi. hieu ve cam ((xuc ban) or (cuc ban)) thanh lai cua tre*.
