Rugby is a game played by two teams each on a rectangular field with goal lines and goal posts at either end. The objective is to run with an oval ball across the opponent's goal line or kick it through the upper portion of the goalposts, with forward passing and time-outs not permitted.

As the name suggests, Rugby sevens features seven players in each team. The whole match is divided into two halves, each half lasting for 7 minutes, and the intermission does not exceed 2 minutes.

Famous moves in rugby are the scrum where packs of opposing players push against each other for possession, and the lineout where parallel lines of players from each team are arranged perpendicular to the sideline in an attempt to catch the ball thrown from the area behind the touch-line.

Rugby was first incorporated into the Asian Games in 1998.

The rugby sevens of the Hangzhou Asian Games will be held in Hangzhou Normal University Cangqian Athletics Field from September 24 to September 26, and the athletes will compete for 2 gold medals.
