Who is the eighteen Niang of Erlongshan Temple in Anyang?

Excuse me, who is the eighteen Niang of Erlongshan Temple in Anyang? Eighteen mothers of Erlongshan Temple in Anyang: Nu Wa Niangniang, Notre Dame de Yuan Jun, Yuan Jun of Bi Xia, Mazu, Doum Yuan Jun, Chang 'e, Queen Mother of the West, Jiutian Xuan Nv, Lady Shangyuan, Queen Houtian, Zhaoling Li Furen, Lady of the Antarctic, Lady Wang Ying, Lady Yunhua, Lady Wang Ziwei, Lady Taizhen, Lady Sanyuanfeng and Taiwei Xuanqingzuo in Yunlin. The eighteen-year-old mother is not a specific person, but a group of people, or a fairy. What's more, anyone named "Niang" is commonly known in the north. Du Guangting, a Taoist priest in the Song Dynasty, wrote a Record of Immortals in Yucheng, which copied female immortals. This is also a feature of Taoism and folk beliefs. On the one hand, it shows more respect for women.
