The formation and evolution of galaxies is one of the most complex and central problems in modern astrophysical research. The build-up of stellar mass through star-forming activities leaves chemical footprints in the interstellar medium of galaxies. Such chemical footprints are further affected by inflows and outflows, both of which are key ingredients for the evolution of galaxies. In the past five years, numerous progress has been made on the observational side by studying the nearby Universe with 3D spectroscopy. By measuring the ISM metallicities through optical emission lines, the interplays between inflows, outflows and star formation can be constrained through chemical evolution models. Recent high spatial resolution observations with wide-field capabilities even start to shed light on metal mixing and stellar feedback on sub kilo-parsec scales. In this talk, I will give an overview of the status in this field of research with an emphasis on my contributions. I will end the talk by an outlook of the key questions to be addressed in the next few years and possible pathways.
