Abstract　 　　
　 It is well-established that galaxies and their central black-holes co-evolve with each other, which indicates that the black hole and the host have good "communication" throughout their evolution. Fueling and feedback are two most important ways of "communication", thus they are key elements for understanding the galaxy evolution. In this talk, I focus on low-luminosity AGNs, and touch a few aspects of their fueling and feedback. Our studies show how AGN fueling can be affected by environments at various scales, ranging from cosmological large-scale structures to the very center around 100pc. In particular, I will talk about studies of fueling and feedback using 2D spectroscopy. In the end, I show how future surveys and projects, such as CHILI (CHIna Lijiang IFU), MaNGA, and HETDEX, can make significant advances in the fueling and feedback of low-luminosity AGNs.
