Perhaps you should try some spelling variations:
hanh lai » hanh lam, hanh tai, thanh lap
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
soc ban » hoc ban, coc ban, soc ba
lai cua » dai cua, hai cua, lai chau
cua tre » cua te, cuu tre, cua triet
so ban » sao ban, so bang, co ban
x hoi » xa hoi, o hoi, x ho

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: tu cac ky nang x hoi. hieu vu cham ((soc ban) OR (so ban)) hanh lai cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu cac ky nang x hoi. hieu vu cham ((soc ban) or (so ban)) hanh lai cua tre*.
