Do you know when you can't play the piano? It is said that when the ancients played the guqin, the rules were strict, and they summed up several situations in which it was inconvenient to play the guqin.

1. The wind and the rain do not bounce. This makes sense. You said that there is a strong wind outside, torrential rain, lightning and thunder, and the atmosphere is not right, so don't play the piano.

2, in the dust city does not play. Think about it, if you are playing the piano in the downtown area, just after you play the piano twice, you will hear the sound of "grinding scissors, cutting kitchen knives", which is really bad for the scenery.

3. Don't play against vulgar people. I think this sentence is the best, art must be shared with those who understand it. If you share your own works with people with different frequencies, you often end up asking for troubles yourself, and it’s okay to not find such troubles, so let’s share elegant art with elegant people.

4. Do not sit or play. This sentence is very straightforward. It is very stable to sit and play. It is in line with the aesthetics of the guqin. It is a basic requirement and will not be explained here.

5. No clothes and no play. Dress up and play, it's the bare minimum of respect for any art form. Not only to dress, but also to dress formally. These details often reflect a person's understanding and cognition of art. These non-playing rules stipulated by the ancients mostly emphasize an atmosphere and show respect for the art of guqin. To respect art is to respect yourself.
