Perhaps you should try some spelling variations:
nhan luc » nang luc
sach vay » sach va, sach hay, sach nay
tu nhan » tue nhan, cu nhan, tu ngan
hieu tu » chieu tu, hieu tuc, hien tu
lang xa » lang ha, dang xay, lang van
va dan » ca dan, va dau, va dap
va dao » ca dao
vi cua » vai cua, di cua
cua te » cua tu

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 vay) OR (sach y)) lang xa hoi. hieu tu nhan luc ((va dan) OR (va dao)) vi cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach vay) or (sach y)) lang xa hoi. hieu tu nhan luc ((va dan) OR (va dao)) vi cua te~".
• Adding a wildcard symbol may retrieve word variants: te ((sach vay) or (sach y)) lang xa hoi. hieu tu nhan luc ((va dan) OR (va dao)) vi cua te*.
