Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve cham » va cham, ve chat, vu cham
danh vi » hanh vi, dinh vi, danh di
cua tre » cua te, cuu tre, cua triet
sach v » sach va, sach 2, sach vay
luc va » tuc va, loc va
vi cua » vai cua, di cua

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: te ((sach v) OR (sach y)) nang xa hoi. hieu ve cham ((luc va) OR (duc va)) danh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach y)) nang xa hoi. hieu ve cham ((luc va) OR (duc va)) danh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach v) or (sach y)) nang xa hoi. hieu ve cham ((luc va) OR (duc va)) danh vi cua tre*.
