First, Shen Zijie and He Xining quarreled on the bench because Qiu Biao's guidance did not adjust the contradiction between them. Shen Zijie and He Xining of Shenzhen team had an altercation on the bench. In fact, Qiu Biao is responsible as the guide of Shenzhen team. Because Shen Zijie and He Xining just had an altercation, the Shenzhen team played half-time. However, when seeing an altercation between Shen Zijie and He Xining, Qiu Biao, as a guide, failed to resolve the contradictions between them in time, which led to their altercation on the bench. To a certain extent, this shows that Qiu Biao ignored the harmony among the players and failed to reconcile the contradictions among the players, which would lead to the escalation of contradictions. So I think the quarrel between Shen Zijie and He Xining on the bench has a lot to do with Qiu Biao's failure to make good use of 15 minutes.
Second, Qiu Biao's decision-making is problematic. In the third quarter, Qiu Biao obviously found that Shen Zijie and He Xining didn't cooperate at all. As a defender, Shen Zijie was completely out of state. He Xining rushed to the basket as long as he got the ball, which actually showed that the two had no intention of cooperating at all. In this case, Qiu Biao, as a guide, should immediately make up his mind to abandon one of the two people. Qiu Biao was not decisive when he should be decisive, which led to the escalation of the contradiction between the two, which in turn affected the whole team's game.
Third, conclusion Although Shen Zijie and He Xining quarreled because of private affairs, their quarrel has affected the team. So I think Qiu Biao is partly responsible.
