Nine-ball bag is a name for playing billiards with nine balls. Dajinjin appears in fancy billiards, including six balls and nine balls. Dajinjiaojin is the main way to score. There is only one way to play Daikin, which is called Daikin. Xiaojin's situation is a little more than Daikin's:

1. When ball 1 and ball 9 are on the table at the same time, clearing the table directly is called Xiaojin.

2. It is also a small gold when the kick-off directly drives the ninth ball.

3. When hitting the ball halfway, passing the No.9 ball is also a gold medal.
