Recent studies over the past decade indicate that the CGM is crucial in bridging the inner parts of galaxies with local large-scale structures, as well as in regulating galaxy formation and evolution. In my talk, I'll begin with an overview of the CGM. Then, I will focus on a specific galaxy: our own Milky Way. Given the abundant data available for the Milky Way, it's an ideal candidate for testing various CGM-related theories and models. I will discuss the gaseous components of its CGM and share findings from several of our group's research projects. Finally, I will explore the prospects of CGM research in light of current and planned observatories and missions, both domestically and internationally.
