Perhaps you should try some spelling variations:
hanh va » hang va, hanh vi
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
luc va » duc va, tuc va
va cua » va chua, via cua, ca cua
loc va » hoc va
sac ky » cac ky
ve cac » va cac, vien cac
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: va ((sac ky) OR (sai ky)) nang xa hoi. hieu ve cac ((luc va) OR (loc va)) hanh va cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "va ((sac ky) OR (sai ky)) nang xa hoi. hieu ve cac ((luc va) or (loc va)) hanh va cua te~".
• Adding a wildcard symbol may retrieve word variants: va ((sac ky) OR (sai ky)) nang xa hoi. hieu ve cac ((luc va) or (loc va)) hanh va cua te*.
