Adiabatic and configuration-fixed constrained triaxial relativistic mean field (RMF) approaches are developed for the first time. A new phenomenon, the existence of multiple chiral doublets (MχD), i.e., more than one pair of chiral doublet bands in one single nucleus, is suggested for ${}^{106}\mathrm{Rh}$ based on the triaxial deformations and their corresponding proton and neutron configurations.
