Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
hieu ve » hieu van
vai cua » dai cua, hai cua, lai cua
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
cam luc » cau luc
tu cai » tu cac, tu can, tu bai
cai ky » cao ky, cac ky, cam ky

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 cai ky nang xa hoi. ((hieu ve) OR (hieu va)) ((cam luc) OR (cam xuc)) va hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cai ky nang xa hoi. ((hieu ve) or (hieu va)) ((cam luc) OR (cam xuc)) va hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu cai ky nang xa hoi. ((hieu ve) or (hieu va)) ((cam luc) OR (cam xuc)) va hanh vai cua tre*.
