We present high-sensitivity and large-scale atomic hydrogen (H i) observations toward lenticular (S0) galaxy NGC 4111 using the Five-hundred-meter Aperture Spherical Radio Telescope. The column-density map shows that NGC 4111 and seven other different types of galaxies share a huge H i gas complex. The data also suggest that NGC 4111 is interacting with seven galaxies. Moreover, we identified a rotating gas disk associated with NGC 4111 from the H i complex. Still, the H i disk rotation direction has deviated from its stellar disk by about 34 ....
