NBA games are divided into three parts: preseason, regular season and playoffs.
After the regular season, the top eight teams in the East, West and League entered the playoff competition. The champions in each division of the East-West League and the second place in the best division constitute the top four seeds, and the other four teams are ranked as the fifth to eighth seeds according to their achievements. The playoffs are elimination. In the first round of the East-West League, the first pair ranked eighth, the second pair ranked seventh, the third pair ranked sixth and the fourth pair ranked fifth. The knockout round will last until the Eastern and Western champions are decided, and then the Eastern and Western champions will play in the finals. Both the playoffs and the finals adopt the seven-game system, and the team with high winning rate in the regular season gains the advantage at home. The home and away games in the playoffs shall be played according to the principle of 2,2, 1, 1, 1 (where the home and away games in the NBA finals were changed from 20 14 to 2-2- 1- 1).
