  The experimental study of the second-order interference with fermions is much
less than the one with bosons since it is much more difficult to do experiments
with fermions than with photons. Based on the conclusion that the behavior of
two identical classical particles has exactly half fermionic and half bosonic
characteristics (PRA \textbf{88}, 012130 (2013)), we have studied the
second-order interference of fermions via the second-order interference of
photons in Hanbury Brown-Twiss and Hong-Ou-Mandel interferometers,
respectively. The experimental results are consistent with the theoretical
predictions, which serve as an efficient guidance for the future interference
experiments with fermions. The employed method offers an interesting and
convenient way to study the coherence of fermions.
