This kind of behavior is undoubtedly commendable. First of all, this shows that Japanese fans have good civic quality and environmental awareness. While enjoying the game, they also respect the public environment and consciously maintain the order of the stadium. Secondly, this kind of behavior sets a good example for fans all over the world and shows the proper civilized characteristics in sports events. Finally, this behavior also reflects the love of Japanese fans for football and their support for the team. They are willing to make their own contribution to protecting the environment and maintaining the order of the stadium.
However, some people have questioned this behavior. In their view, although the act of picking up garbage is commendable in itself, it seems to be suspected of deliberate speculation after winning the competition. In this regard, we need rationality. Whether it is sincere behavior or for the purpose of hype, it is meaningful as long as it can attract people's attention and let more people participate in environmental protection actions.
Generally speaking, Japanese fans take the initiative to pick up rubbish after winning Germany in the competition, regardless of their motives, which reflects their civic quality and environmental awareness and is worth learning and learning from.
