After a few years, what kind of living conditions should human beings successfully create if they want to immigrate to Venus?

Venus is too close to the sun, so we must first overcome the problem of temperature control. By controlling the temperature, water can be preserved in liquid state, oxygen can be separated by water, and human beings can survive. All production and life can be carried out at room temperature. Secondly, it should be to overcome gravity, which should be relatively easy. There are already good technologies at present. However, it may be too small to immigrate to Venus, so it is much easier to consider moving to Mars.
