Galactic chemical evolution is mainly regulated by galaxy internal star formation and external matter exchange with the environment (i.e. gas accretion and outflow winds). Therefore, understanding the chemical evolution of a galaxy is a valuable way to probe the roles played by these processes in driving galaxy formation and evolution. Thanks to the advent of many massive stellar and galaxy surveys in the last decade, we now have abundant chemistry observations in the Milky Way and other galaxies, which are still rapidly increasing and impose unprecedented constraints on galactic chemical evolution. Because of dramatic differences in the observations of the Milky Way and other galaxies, studies on their chemical evolution have taken very different perspectives. In this talk, I will provide an overview of recent interesting results obtained by modelling the new chemistry observations in the Milky Way and external galaxies separately. At the end of the talk, I will share my own prospect on the future galactic chemical evolution studies in terms of linking the Galactic and extragalactic observations together.
