Perhaps you should try some spelling variations:
hanh dai » hanh tai, hanh dao, vanh dai
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
hieu vu » hieu va, hieu ve, hieu su
luc va » duc va, tuc va, loc va
te sac » te sach, te cac, te san
xuc va » duc va, tuc va, xac va
sac ky » cac ky, sai ky
cua te » cua tu

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: te sac ky nang xa hoi. ((hieu vu) OR (hieu van)) cham ((xuc va) OR (luc va)) hanh dai cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang xa hoi. ((hieu vu) or (hieu van)) cham ((xuc va) OR (luc va)) hanh dai cua te~".
• Adding a wildcard symbol may retrieve word variants: te sac ky nang xa hoi. ((hieu vu) or (hieu van)) cham ((xuc va) OR (luc va)) hanh dai cua te*.
