Perhaps you should try some spelling variations:
hanh dai » hanh tai, hanh dao, vanh dai
ky tang » ky dang, kho tang, ky trong
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
xuc van » duc van, luc van, vuc van
cua tre » cua te, cuu tre, cua triet
tu bai » tu ban, tu bat, te bai
ma hoi » mai hoi, xa hoi, ma hoa

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 bai ((ky tang) OR (ky nang)) ma hoi. hieu ve cham ((xuc van) OR (duc tan)) hanh dai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu bai ((ky tang) OR (ky nang)) ma hoi. hieu ve cham ((xuc van) or (duc tan)) hanh dai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu bai ((ky tang) OR (ky nang)) ma hoi. hieu ve cham ((xuc van) or (duc tan)) hanh dai cua tre*.
