What is this scene that often appears in Japanese anime? Is there any special purpose?

This is a wind chime. It won't ring when there is no wind, but it will ring when there is wind.

This is a bell commonly used in Japan.

The function of wind chimes is to give people a cool feeling.

The sound of wind chimes is very similar to the sound of insects in autumn. Listening to the sound of wind chimes in summer can be better, and it can play the role of looking at plums and quenching thirst.
