Perhaps you should try some spelling variations:
van cham » van chat, van tham, va cham
hieu van » hieu va, thien van, lieu va
danh van » doanh van, dang van, dinh van
van cua » vang cua, ban cua, dan cua
sach le » cach le, sach lo, sach kem
dang xa » dang xay, lang xa, dang ha
sach de » cach de, sach dao, sach dat
cua tre » cua te, cuu tre, cua triet
luc va » duc va, loc va
tuc va » thuc va, truc va, tuc xa

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 ((sach le) OR (sach de)) dang xa hoi. hieu van cham ((luc va) OR (tuc va)) danh van cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach le) OR (sach de)) dang xa hoi. hieu van cham ((luc va) or (tuc va)) danh van cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach le) OR (sach de)) dang xa hoi. hieu van cham ((luc va) or (tuc va)) danh van cua tre*.
