Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
hanh hai » thanh hai, nhanh hai, hang hai
tan hanh » tan thanh, tang hanh, toan hanh
cua tre » cua te, cuu tre, cua triet
hai cua » thai cua, dai cua, hoi cua
ky tang » ky nang, ky dang, kho tang
tang xa » trang xa, tang ma, lang xa
hieu ve » hieu va
cam duc » cam xuc, cao duc, pham duc
su cac » tu cac, su cao, eu cac
su can » su van, su cao, tu can

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: ((su cac) OR (su can)) ky tang xa hoi. ((hieu ve) OR (hieu van)) cam duc tan hanh hai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su cac) OR (su can)) ky tang xa hoi. ((hieu ve) or (hieu van)) cam duc tan hanh hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((su cac) OR (su can)) ky tang xa hoi. ((hieu ve) or (hieu van)) cam duc tan hanh hai cua tre*.
