What are the rules of basketball? Tell me about it, will you?

Basic rules of basketball 1) Basic rules 1: 1. Competition mode: A team consists of five people, one of whom is the captain, and the maximum number of substitutes is seven, but the number can be increased according to the organizer. The game is divided into two halves, each half is 20 minutes, and the intermission is 10 minutes. At the end of the game, if the two teams have the same points, overtime will be played for 5 minutes. If the score is still the same after 5 minutes, a 5-minute overtime will be played again until the tie is broken. 2. The scoring category is scoring after the ball is thrown into the basket and approved by the referee. 3 points can be scored for the inner input of the branch line; You can get 3 points for shooting outside the three-point line and 1 point for free throws. 3. How to start the game? Each team pushes a jumper to the central jumper area, the referee throws the ball, and the jumpers from both sides start the game. Throw a foul ball. 4. Players can change each player within 20 seconds, and the number of changes is unlimited. The time to exchange players is when someone fouls, fights for the ball, calls a timeout, etc. The referee can temporarily suspend the timing of the game. 5. Free throws Each player has four chances to be fouled, and the fifth foul will be full and quit. And cannot be played again in the same game. Free throw is shooting when no one can stop or defend it. It is a punishment for the offending party and an opportunity for the opposing party. Stand behind the free throw line and shoot within 5 seconds after receiving the referee's ball. After shooting, you can't cross the free throw line before the ball touches the basket. 6. Violations can be roughly divided into (1) ordinary violations, such as taking the ball away, dribbling it twice, kicking the ball with your feet or hitting the ball with your fist. (2) jump ball violation, (3) jump ball violation: the jumper can enter the central jump ball area before the jumper touches the ball. 2) Basic Rule 2: The 30-second rule-When the attacker is in possession of the ball on the court, he must make a shot within 30 seconds (24 seconds in NBA and 35 seconds in NCAA). 10 second rule-the team must make the ball enter the frontcourt (the opposing half) within 10 second. The player must throw the foul ball within 5 seconds. FIBA rules stipulate that free throws must also be made within 5 seconds (NBA rules are 10 seconds). The 3-second rule-physical contact with the opponent causes a foul, such as an argument with the referee. Personal foul-a foul caused by physical contact with the other side. Technical foul-A player or coach is convicted of a foul for poor performance, such as an argument with the referee. Cancel the foul of competition knowledge-a foul that does not reflect the spirit of athletes, such as hitting people. After this happens, the player should be sent off immediately. Player fouls five times-whether it's a personal foul or a technical foul, a player must leave the court for five times (NBA rules are six times). Foul-violation of rules, neither personal nor technical. The main violations are: illegal dribbling; Take the ball away; 3 seconds violation; Get the ball out of bounds. Player Out of bounds-The ball is out of bounds when the player takes the ball or touches the line or out of line area. The ball is not out of bounds in the air until it touches the line or off-line area. Disturb the ball-when the shot ball falls to the basket, neither player can touch the ball. Defenders are not allowed to touch the ball when it is under the basket. Players who are closely watched-dribbling or shooting, otherwise the team will lose possession of the ball (which is not stipulated in NBA rules). The ball will go back to the backcourt-if the team has moved the ball from the backcourt to the frontcourt, then the players of the team can no longer move the ball across the center line and transport it back to the backcourt.
