Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
te sach » toc sach
van lam » van nam
xang xa » mang xa, ang xa, dang xay
lang xa » lang ha, dang xay, lang van
cua tre » cua te, cuu tre, cua triet
luc va » duc va, tuc va
loc va » hoc va
va cua » va chua, via cua, ca cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y ((xang xa) OR (lang xa)) hoi. hieu van lam ((luc va) or (loc va)) hang va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y ((xang xa) OR (lang xa)) hoi. hieu van lam ((luc va) OR (loc va)) hang va cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((xang xa) OR (lang xa)) hoi. hieu van lam ((luc va) or (loc va)) hang va cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y ((xang xa) OR (lang xa)) hoi. hieu van lam ((luc va) or (loc va)) hang va cua tre*.
