Perhaps you should try some spelling variations:
ve nhan » de nhan, va nhan, ve phan
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
sach v » sach va, sach 2, sach vay
ve nha » ke nha
luc va » duc va, tuc va, loc va
va dan » ca dan, va dao, va dau
dan vi » doan vi, don vi, dan 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 nhan) OR (ve nha)) luc va dan 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 nhan) OR (ve nha)) luc va dan vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach v) or (sach y)) nang xa hoi. hieu ((ve nhan) OR (ve nha)) luc va dan vi cua tre*.
