Who can help me explain what are the fouls in basketball, such as how to add them outside the step?

One: defense 1) defensive foul is too obvious; Block when the opponent has started to lay up (block foul); When the opponent has started shooting or layup; Defensive three seconds; Disturb the ball (count as a violation) 2: attack 2) Offensive foul, unreasonable collision (three steps with the ball), dribbling twice (the easiest to commit, start with the ball, clap your hands and clap your hands again); The opponent stands still in the three-second zone, and the attacker still insists on layups, which is an offensive foul; Cover foul, three-ring foul, stepping foul

It's not illegal to walk ... In addition, it's illegal to turn your wrist and dribble the ball twice, and it's illegal to interfere with the ball ... Fouls are generally thugs, blocks, hitting people with the ball, etc ... The rules of NBA and FIFA are different ... There is a reasonable collision zone on the curve of NBA ... And the interference ball is also different from FIFA ... Shooting, layup and other common interference balls are also punished ... But when the ball is not,

1. The batter fouled (touching the player's hand before touching the ball or not touching the ball directly when defending or stealing).

2. Move the pick-and-roll (move your body when you cover your teammates with the ball)

3 pulling people (illegally obstructing each other's actions with their arms, etc.). )

4 hit people (I understand)
