Both observations and numerical simulations have clearly shown the existence of winds from black hole hot accretion flow. I will introduce the finding histories of wind by numerical simulations. I will also introduce the driven mechanisms of wind. The detailed properties (e.g. temperature, energy and momentum fluxes carried by wind) of wind are also calculated along the trajectories of wind. In the accretion flow with very low accretion rate, such as the accretion flow in our Galactic Center, the plasmas are dilute and collision-less. How do the properties of wind change in the collision-less limit are also studied. Finally, I introduce the observational applications of wind.
