Ziyun Mountain(紫云山):
In Chinese, it is pronounced as: zǐ yún shān，Written as:

Ziyun Mountain is a high mountain featured in “Journey to the West,” where the enlightened Bodhisattva Pilanpo cultivated her spiritual practices.
Bodhisattva Pilanpo resides in Qianhua Cave on Ziyun Mountain. She is the mother of the star official Mao Ri from the Twenty-Eight Constellations, and possesses limitless magical power, embodying great compassion and mercy. However, her true form is unclear. In the original text, Sun Wukong speculates that her true form might be that of a hen, although it is not explicitly stated; she could be one of the ten Rakshasa women mentioned in the Lotus Sutra or a hen.
In the seventy-third chapter of “Journey to the West,” Tang Seng and Eight Precepts along with their fellow disciple are captured by the centipede spirit, the Hundred-Eyed Demon Lord, after being poisoned by jujube tea. In the midst of battle, the centipede spirit emits a golden light from the thousand eyes under its ribs, trapping Wukong. Unable to prevail, Wukong is fortunate when Laishan Laomu, disguised as a paper-burning woman, advises him to seek help from Bodhisattva Pilanpo at Qianhua Cave on Ziyun Mountain. Bodhisattva Pilanpo throws a precious embroidered needle, forged from the solar eye of her son, the star official Mao Ri, into the sky, shattering the Demon Lord’s golden light. With a simple gesture, Bodhisattva Pilanpo reveals the centipede’s true form and takes it away to guard the gates. After thanking the Bodhisattva, Wukong sets fire to the Yellow Flower Temple, packs up their belongings, and continues their journey westward with his master and brothers.
