  A time-reversal Bell test protocol is proposed. The quantum states are
prepared by faraway separated partners and transferred to the third partner who
carries out Bell basis measurement on them to post-select the
Einstein-Podolsky-Rosen (EPR) pairs. If some loopholes open, similar as that in
normal Bell test, the Bell violation in the present protocol is apt to be
interpreted with local hidden variable (lhv) theory. With some modifications on
the protocol, the lhvs at both sides are prevented to exchange their
information. Thus they only function locally and cannot affect the behaviors of
the states at the other sides. However, Bell violation can still be obtained in
this case. It means that Bell violation is realized with the lhv theory
excluded. Because high detection efficiency is not compulsory, this protocol
can be realized with present technology.
