Progresses of the chirality in atomic nuclei are reviewed, in particular, the recently proposed collective Hamiltonian based on tilted axis cranking approach to describe chiral vibration and rotation modes, and the experimental achievements for chirality and multiple chiral doublets, i.e., in 106 Ag, 133 Ce and 103 Rh. The first experimental evidences of multiple chiral doublet bands with distinct and identical configuration found in 133 Ce and 103 Rh are discussed in detail.
