  The paradox on the previous interpretation for the nuclear chiral geometry
based on the effective angle has been clarified by reexamining the system with
the particle-hole configuration $\pi (1h_{11/2})^1 \otimes \nu(1h_{11/2})^{-1}$
and rotor with deformation parameter $\gamma=30^\circ$. It is found that the
paradox is caused by the fact that the angular momentum of the rotor is much
smaller than those of the proton and the neutron near the bandhead. Hence, it
does not support a chiral rotation interpretation near the bandhead. The
nuclear chiral geometry based on the effective angle makes sense only when the
angular momentum of the rotor becomes comparable with those of the proton and
the neutron at the certain spin region.
