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