The LMC cluster NGC 1978 shows different properties in the two parts divided by its minor axis. These two parts have different color distributions of the core He-burning (CHB) stars and giant branch (GB) positions on the CMDs at and below the level of the CHB stars. These differences may be caused by spread in metallicity.
