  The chiral geometry of the multiple chiral doublet bands with identical
configuration is discussed for different triaxial deformation parameters
$\gamma$ in the particle rotor model with $\pi h_{11/2}\otimes \nu
h_{11/2}^{-1}$. The energy spectra, electromagnetic transition probabilities
$B(M1)$ and $B(E2)$, angular momenta, and $K$-distributions are studied. It is
demonstrated that the chirality still remains not only in the yrast and yrare
bands, but also in the two higher excited bands when $\gamma$ deviates from
$30^{\circ}$. The chiral geometry relies significantly on $\gamma$, and the
chiral geometry of the two higher excited partner bands is not as good as that
of the yrast and yrare doublet bands.
