Volleyball is one of the ball games. This stadium is rectangular with a high net in the middle. Both sides (6 players from each side) occupy one side of the court, and the players hit the ball from the net with their hands. The ball used in volleyball is made of sheepskin or artificial leather with rubber bladder, which is about the size of a football.

The volleyball competition venue is a rectangle of 18m× 9m, with at least 2m open space around and no obstacles at least 7m above the venue. Draw a line in the middle of the court and divide the court into two equal areas. All lines are 5 cm wide. The circumference of the ball is 65-67 cm, the weight is 260-280 g, and the air pressure is 0.40-0.45 kg/cm2.
There is a net on the center line of the site. The net is 1 m wide and 9.50m long, and it is hung on two posts outside the stadium. The height of women's net is 2.24 meters, and that of men's net is 2.43 meters. At the junction of the two ends of the net perpendicular to the sideline and the center line, there are 5 cm wide sign belts respectively, and a sign pole with a length of 1.80 m is connected to the outside of the sign belt.
Players usually don't need to master all six skills, such as serving, passing (catching), passing (lifting), spiking, blocking and saving the ball, and usually specialize in one or more of them according to the team's tactics. The most common position assignment includes three positions: the attacker (divided into the main attacker and the auxiliary attacker), the setter and the free man (full-time defensive player). In order to effectively stop the opponent's attack before the opponent has enough reaction time, and bounce the ball back to the opponent's field at a steep angle and high speed, generally speaking, a player with tall figure and good bouncing ability is the attacker.
