At the same time, the action of stir-frying and the sound of ingredients tumbling in the pot are like the bass part of music, deep and powerful.

2. Faucet sound: When the faucet is turned on, the sound of water spewing out and hitting the edge of the container is like the tapping sound of a piano or violin, crisp and powerful. The sound of water flowing in the pipeline is more like the continuous sound of flute or clarinet, melodious and continuous.
