22 into 8 in the basketball game, to ensure fairness, how should I play?

Generally speaking, the fairest way is to draw lots. 10 teams will advance directly to 16, and the remaining 12 teams will draw lots to decide to participate. The winners will advance to 16, and then they will compete in groups to determine the number of places in the top 8. In this way, the strong team can advance to the top 16 through their own strength, while the weak team will be eliminated sooner or later, so the overall result has little impact.
