Perhaps you should try some spelling variations:
cua viet » ca viet, hoa viet, cua vat
nang xa » nang x, lang xa, nang ma
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
soc van » hoc van, oc van, sac van
sat van » sat va, hat van, hoat van
tu sai » tu bai, tu san, tu cai
sai ky » sac ky
anh ve » hanh ve, anh viet, thanh ve
anh va » hanh va

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 sai ky nang xa hoi. hieu vu cham ((soc van) OR (sat van)) ((anh ve) OR (anh va)) cua viet~.
• Adding a wildcard symbol may retrieve word variants: tu sai ky nang xa hoi. hieu vu cham ((soc van) or (sat van)) ((anh ve) or (anh va)) cua viet*.
