What are some of the regulations in badmington?

In Badminton, key regulations include the dimensions of the court, which measures 13.4 meters long and 6.1 meters wide for doubles, and the height of the net, set at 1.55 meters. Players must serve underhand from below the waist, and the shuttlecock must be struck before it crosses the service line. Points are scored in a rally scoring system, where matches are typically played to 21 points, and a player must win by at least 2 points. Additionally, players are not allowed to hit the shuttlecock twice in succession or touch the net during play.
