How to play basketball is a key problem.

I am a national first-class referee with a referee certificate. From a professional point of view, there are no two kinds of fouls: pinching and hitting. I reasoned, do you want to ask the arrested person (guard against 2 when closing the door 1) to hit people (thugs &; Malicious hitting foul)

Attack: When the attacker breaks through, it depends on whether the defender's feet stand firm. If he stands steady and there is no foul on his upper limbs, then he won't stop the foul. On the contrary, if he stands steady, his upper limbs don't make any aggression in the cylinder, he makes physical contact with the defender, and the defender falls to the ground or retreats after being hit, it is judged as an offensive foul.

When dribbling, the batter will serve the sideline ball, and if there are more than four fouls in a single quarter, he will make a free throw. When the shooter shoots, he makes a free throw.

Deliberately hitting people: that is a violation of sports ethics, and 2 penalties 1 throwing are taken. If the circumstances are serious, direct expulsion!
