Perhaps you should try some spelling variations:
cua tre » cua te, cuu tre, cua triet
hang di » hang doi, hang vi, hang dien
sac ky » cac ky, sai ky
di cua » dai cua, doi cua, de cua
tu sac » tu sach, tu cac, tu san
ve ban » te ban, va ban, ve bao
ve bac » ve bao, ve cac, he bac
bo va » bao va, so va, co va
do va » do van, so va
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 sac ky nang x hoi. hieu ((ve bac) OR (ve ban)) ((bo va) OR (do va)) hang di cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang x hoi. hieu ((ve bac) or (ve ban)) ((bo va) or (do va)) hang di cua tre*.
