[en] Based on the triaxial particle-rotor model (PRM), the chiral doublet bands with symmetric particle-hole configurations πg_9/2 direct x νg_9/2^-1, πh_11/2 direct x νh_11/2^-1 and asymmetric configurations πg_9/2^-1 direct x νh_11/2, πh_11/2^-1 direct x νi_13/2 have been investigated, including their rotation spectra, the relations between spin and rotational frequency, and the reduced B (E2), B(M1) transition probabilities. These configurations correspond to regions A∼100, A∼130 and A∼170 in nuclear chart respectively. It is observed that the larger angular momentum provided by the valence nucleons, the higher the spin corresponding to the appearance of the chiral doublet bands, and the broader their spin interval. The chiral bands based on asymmetric configurations exhibit quite similar properties as those on symmetric ones, and can be discovered in future in-beam γ experiments
