"Originally, the ancestors had already decided to abandon this place, but they no longer had the ability to find another, better location. It was at that time that a young member of the clan discovered a pattern: everyone who went mad in their dreams had heard a strange melody right before falling asleep.
Later, it was discovered that by covering this sound with other noises, the people in the city would not be affected.
At that time, they were fleeing, so musical instruments were naturally scarce.
So the ancestors developed this method of using stones as instruments. As they lived there longer, it eventually had a formal name called 'Zhu'. Later, these Zhu came in more and more forms and styles, gradually forming today's melodies."
