Introduction to the seven wonders of black

The Black Seven Miracle means that the seventh team beat the second team in the NBA playoffs. The NBA playoffs are divided into two regions: East and West. Eight teams from each region entered the playoffs. Regular season record ranking determines the relationship, the first pair is eighth, the second pair is seventh, the third pair is sixth, and the fourth pair is fifth. Among them, the team with good actual combat record has home court advantage. Because there is a considerable gap in strength between the team ranked second and the team ranked seventh, it is a miracle to beat the second in the seventh place, which is called the "Black Seven Miracle".
