Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
hanh vai » hanh vi, hanh tai, hanh van
nang xa » nang x, lang xa, nang ma
van cam » van nam, van lam, van cau
hanh va » hang va, hanh vi
cua tre » cua te, cuu tre, cua triet
su cac » tu cac, su can, eu cac
su cao » cu cao, vu cao, su co
xuc va » duc va, tuc va, luc va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((su cac) OR (su cao)) ky nang xa hoi. hieu van cam xuc va ((hanh vai) or (hanh va)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su cac) OR (su cao)) ky nang xa hoi. hieu van cam xuc va ((hanh vai) OR (hanh va)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su cac) OR (su cao)) ky nang xa hoi. hieu van cam xuc va ((hanh vai) or (hanh va)) cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su cac) OR (su cao)) ky nang xa hoi. hieu van cam xuc va ((hanh vai) or (hanh va)) cua tre*.
