What qualifications do you have to stay in the dungeon?

Draw lots to choose. In the film of wandering the earth, there is a setting that all human beings on the earth will draw lots to select their qualifications and randomly select half of them to enter the underground city. The film tells a bold plan called "Wandering Earth" put forward by human beings to save themselves, that is, to build tens of thousands of engines and steering gears on the surface of the earth and push the earth out of the solar system.
