I tied the sacred string to the wood and noticed the difference. I was very happy.
When you pluck it, it sounds loud and clear, and the sound seems to be hidden in the strings and will not disappear for a long time, so it is named "hidden".
When the sacrificer heard it, he looked at it and said: "The whole body is white with gleaming scales. The ancient dragon-bearded harp was very beautiful, but it is not like this. The sound of this harp is faint as clouds, so it must be a rich legacy of the gods."
Later it was called "Yinyin Qin" because of this.
In fact, it is to express my love to Yin Yinqin-kun~~~~(>_
