Introduce the temporary transfer system of domestic and foreign aid: after the regular season, the top eight teams can choose one domestic aid and one foreign aid from the teams that have never entered the playoffs in the order of foreign aid delisting and domestic aid delisting. The selected domestic aid must be a member of the national training team or an excellent player in the top ranking of technical statistics in the regular season. In this way, the national team or semi-national team players in the weak team don't have to worry about the problem of no ball to play, and the top eight teams have an extra domestic and foreign aid quota because of the playoffs, which makes the gap between teams smaller and increases the degree of competition.
