Perhaps you should try some spelling variations:
thien van » thi van
hieu ve » hieu va, hieu van
hanh va » hang va, hanh vi
loc va » hoc va
va cua » va chua, via cua, ca cua
tu sac » tu sach, tu cac, tu san
luc va » duc va, tuc va
sac ky » cac ky, sai ky
cua te » cua tu
x hoi » xa hoi, o hoi, x ho

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky nang x hoi. ((hieu ve) or (thien van)) cam ((luc va) OR (loc va)) hanh va cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang x hoi. ((hieu ve) OR (thien van)) cam ((luc va) OR (loc va)) hanh va cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang x hoi. ((hieu ve) or (thien van)) cam ((luc va) OR (loc va)) hanh va cua te*".
