After the first two rounds of the game, cheng Haiyan won both the first and second rounds, but the opponent caught up and won the third and fourth rounds. The score is now 2 - 2, and cheng has won the game by outscoring the opponent by 59 points. The opponent can pocket the pink and win the game easily, but cheng will win by winning the last two blacks. This is because the opponent made a mistake by making the cue ball hit the jaws of the table instead of the ball. If the opponent does not escape from the table because the ball does not touch any object, the player will receive a penalty of four points. .
