The X-ray-emitting hot gas is one of the primary components of the X-ray emission in normal galaxies and is crucial for understanding the evolution of the galactic ecosystem. The Virgo Cluster is the nearest and a rich galaxy cluster at its early evolutionary stage, which offers a great opportunity to study the hot gas content of its member galaxies and the cluster environmental effects. In this talk I will introduce a systematic study of the diffuse hot gas around member galaxies residing in the Virgo cluster, based on eROSITA first all sky survey, to test the X-ray scaling relations and understand the roles of cluster environmental effects and galactic outflows in regulating the hot gas content of galaxies. Our results start to provide fresh and crucial X-ray observational constrains to the modern galaxy cluster simulations.
