Since the birth of galaxies, most of their stars have formed in clusters, making the evolution of galaxies and star clusters inseparable. The globular clusters that formed in the early Universe, with their extremely high stellar densities, challenge existing theories of stellar and galactic evolution. During this talk, I will reveal the connections between the recent works of our research group, under the background of Milky Way evolution, including (1) the chemical evolution of the Sculptor dwarf galaxy, (2) the ripples of the galactic disk, (3) the star clusters of the Sagittarius dwarf galaxy, and (4) the escaped stars from globular clusters. Finally, I will also compare the studies of globular clusters in local-group galaxies and high-redshift galaxies to obtain a more complete evolutionary picture.
