Black hole accretion is a fundamental physical process in the universe. It plays an important role in many fields of astrophysics, ranging from AGNs, black hole X-ray binaries, Gamma-ray bursts, to tidal disruption events. Many important progresses have been made in recent years, mainly attributed to the rapid development of numerical simulations. In this talk, I will first give a general introduction to accretion, then I will talk about some important progresses, including wind production from hot accretion flow, super-Eddington accretion, and jet formation.
