  We compute the pseudo entropy in two-dimensional holographic and free Dirac
fermion CFTs for excited states under joining local quenches. Our analysis
reveals two of its characteristic properties that are missing in the
conventional entanglement entropy. One is that, under time evolution, the
pseudo entropy exhibits a dip behavior as the excitations propagate from the
joined point to the boundaries of the subsystem. The other is that the excess
of pseudo entropy over entanglement entropy can be positive in holographic
CFTs, whereas it is always non-positive in free Dirac fermion CFTs. We argue
that the entropy excess can serve as a measure of multi-partite entanglement.
Its positivity implies that the vacuum state in holographic CFTs possesses
multi-partite entanglement, in contrast to free Dirac fermion CFTs.
