Basketball jump rules?

The third paragraph of Article 60 of the Basketball Rules stipulates that the free throw player: 1. Must be in position within the semicircle behind the free throw line; 2. Can shoot in any way. 3. When the referee puts the ball at his disposal, the ball must be released within 5 seconds; 4. The ball must not touch the free throw line or the ground in front of the free throw line before it touches the basket; 5. No fake free throws are allowed ; 6. The ball shall not be touched while it is flying towards the basket; 7. During a free throw, when the ball comes into contact with the rim, no player on either side shall touch the basket or backboard; 8. During any free throw before the last free throw; , he shall not touch the ball or the basket as long as the ball has a chance to enter the basket. Violation of paragraph 3 is a violation. Regarding free throws, there is no rule against taking off. But because most people don't jump when shooting free throws, some people think it's because the rules stipulate that jumping is not allowed. Stop thinking like that, it will make people laugh on the court. You can jump shot, but because people who know how to play can't jump from such a close distance! (Because it's on the same spot), so no one uses jump shots, but if you want to shoot 100%, you can.
