It is said that when Pangu created heaven and earth, the pure air rose to become the sky and the turbid air descended to become the earth. At that time, Pangu felt anxious and urinated. Later, Nuwa passed by here when she was patching up the sky, which was also convenient. After the reincarnation of time and the essence of the sun and the moon, a peach tree grew here. Due to the heavy yin energy, the bark of the peach tree is blue, and the leaves of the peach tree are blue, so this place is called blue peach. As time passed and dynasties changed, the name has been used to this day.
