Bixia Yuanyuan is also known as “Taishan Yunv” (the Jade Maiden of Mount Tai), and her full name is “Dongyue Taishan Tianshi Yunyu Bixia Yuanyuan” (the Jade Maiden of Mount Tai, Heavenly Immortal of the Eastern Peak, Bixia Yuanyuan). She is commonly known as “Taishan Granny” (Grandma of Mount Tai). She is one of
As for the origin of Bixia Yuanyuan, one theory is that she was the Jade Maiden sent by the Yellow Emperor. According to the records of “Jade Maiden Study” and “Record of the Fairy Pool”, when the Yellow Emperor built the Mount Tai Temple, he sent seven women in advance, wearing cloud-shaped crowns and feathered clothes, to Mount Tai to welcome Xikun the Immortal. The Jade Maiden was the one who had attained immortality through cultivation among the seven women. Another theory is that she was the Jade Maiden of Mount Hua. However, she is generally regarded as the goddess of Mount Tai, the daughter of the god of Mount Tai. According to the “Biography of the Jade Maiden” in the Mingwang Zhi Gang: “The Jade Maiden of Mount Tai is a celestial fairy. She was first seen during the reign of the Yellow Emperor and again during the reign of Emperor Ming of the Han Dynasty.” One theory is that she was a commoner named Shi Yuye from the Han Dynasty who possessed supernatural powers. According to the “Jade Maiden Scroll”, during the reign of Emperor Ming of the Han Dynasty, in the Suningfu Fengfu County of the Xiniu Kingdom, the wife of the virtuous Shi Shoudao gave birth to a daughter at 
18th day of the 1st lunar month, at 11 pm, she gave birth to a daughter, named Yu Ye. She was beautiful and intelligent, understood human relationships at the age of three, listened to the Dharma at the age of seven, and worshipped the Queen Mother of the West. At the age of 14, she suddenly felt her mother's teachings and wanted to go into the mountains. She was guided by the Taoist immortal Cao and entered the Huanghua Cave in the Tian Kongshan to cultivate. Tian Kongshan is the name of Mount Tai, and the cave is where the stone house is. There is a pond at the top of the mountain, called the Yu Nv (Jade Maiden) Pond; next to it is a stone statue of the Jade Maiden. This shows that the story of the Taishan Goddess already existed in the Han and Jin dynasties. The Han people also carved a stone statue of the goddess on the top of Mount Tai, and built the Yu'nvchi (Virgin's Pool) at the very top of Mount Tai to worship her. During the Five Dynasties period, the temple collapsed and the stone statue fell to the ground, and the statue of the Golden Boy was eroded and worn away. The Virgin also fell into the Yu'nvchi (Virgin's Pool) at the top of Mount Tai. Emperor Zhen of the Song dynasty went to Mount Tai for an imperial pilgrimage in the east and stayed in his imperial tent. He washed his hands in the Yu'nvchi (Virgin's Pool), and a stone man floated to the surface. Emperor Zhen Zong of the Song Dynasty then ordered the pool to be dredged, the statue of the goddess to be re-carved in white jade, and the local authorities to build a shrine and rename it “Zhaozhen Temple”. He also sent envoys to pay homage to the goddess, calling her “the daughter of the Holy Emperor” and bestowing upon her the title “Tianxian Yunv Bixia Yuanyun”. During the Ming Dynasty, Zhaozhen Temple was renamed “Lingying Palace” and later expanded and enlarged to become Bixia Palace. It was given the title “Bixia Yuanyun”. Taoism absorbed the above beliefs and believes that Bixia Yuanyuan was born in response to the nine qi, was ordered by the Jade Emperor to become a celestial immortal, and oversees all good and evil on earth.
In the northern region of China, the people's belief in Bixia Yuanyuan is extremely strong, and believers worship her as a god who answers prayers. The “Taishan Niangniang Baojuan” (Taishan Niangniang's Sacred Scroll), which popularly narrates the spiritual deeds of Taishan Niangniang, is also revered by Taoism as a scripture and included in the list of Taoist books. The title “Bixia Yuanyuan” is not exclusive to Taishan Niangniang. The Southern Tianfei Shun'yi Lady also has this title, and “The Investiture of the Gods” also says that Yu Hualong is the main pox Bixia Yuanyuan. It was not until modern times that the name Bixia Yuanyuan became exclusively Taishan Niangniang's.
In addition, the folk legend of Bixia Yuanyuan is even more powerful, able to bless farming, business, travel, and marriage, as well as heal the sick and save people, especially enabling women to give birth and children to be healthy. Therefore, in the old days, women believed in Bixia Yuanyuan with particular piety. Not only were there temples on Mount Tai, but there were also many “Niangniang Temples” built all over the place, often with the four Niangniang deities of Child-Sending Niangniang, Child-Expelling Niangniang, Vision Niangniang, and Smallpox Niangniang worshipped alongside. This belief is still thriving today, and people still go to the top of Mount Tai, no matter the effort, to make wishes and pray, and the incense is never-ending.
The birthday of Bixia Yuanyuan is the 18th day of the 4th lunar month, or the 15th day of the 3rd lunar month, and grand celebrations are held at the Bixia Temple on Mount Tai and at temples and shrines dedicated to Bixia Yuanyuan.

   碧霞元君又称“泰山玉女”，全称“东岳泰山天仙玉女碧霞元君”，民间俗称为“泰山奶奶”。道教所奉女仙尊神之一。
至于碧霞元君的来历，一说为黄帝所遣之玉女。据《玉女考》和《瑶池记》记载：黄帝建岱岳观时，曾经预先派遣七位女子，云冠羽衣，前往泰山以迎西昆真人，玉女乃—七女中的修道得仙者。—说为华山玉女。但—般作为泰山女神，为泰山神之女。据明王之纲《玉女传》：“泰山玉女者，天仙神女也。黄帝时始见，汉明帝时再见焉。”一说为汉代民女石玉叶，凭灵泰岱。据《玉女卷》称：汉明帝时，西牛国孙宁府奉符县善士石守道妻妻金氏，中元七 
年甲子匹月十八曰子时生女，名玉叶。貌端而生性聪颖，三岁解人伦，七岁辄闻法，尝礼西王母。十四岁忽感母教，欲入山，得曹仙长指，入天空山黄花洞修焉。天空盖泰山，洞即石屋处也。山顶故有池，名玉女池；旁为玉女石像。可见汉晋时早有泰山神女的故事。汉代人还在泰山顶上雕刻神女石像，在泰山极顶修建玉女池以奉祀。五代时殿堂倾塌，石像仆地，金童之像漫涣剥蚀，玉女也沦落于泰山岳顶玉女池内。宋真宗东封泰山，还次御帐，在玉女池中洗手，一石人浮出水面，此乃玉女。宋真宗于是下令疏浚该池，用白玉重雕玉女神像，命有司建祠并更名为“昭真祠”，遣使致祭，号为“圣帝之女”，封“天仙玉女碧霞元君”。明朝时，将昭真祠又更名为“灵应宫”，后又扩建，增大规模，为碧霞宫。赐号“碧霞元君”。道教吸收了上述信仰，认为碧霞元君乃应九炁而生，受玉帝之命，证位天仙，统摄岳府之神兵天将，并照察人间一切善恶之事。
在我国的北方地区，民众对碧霞元君的信仰极盛，信徒以之为奉神，祷之即应。在民间广为流行宣扬叙述泰山娘娘灵迹的《泰山娘娘宝卷》，道教也奉为教门经籍，纳入道书之列。碧霞元君的称号，也并非泰山娘娘的独有，南方的天妃顺懿夫人也有此号，《封神演义》又说余化龙为主痘碧霞元君。直到近代，碧霞元君之名才为泰山娘娘开专有。
另外，民间传说的碧霞元君更神通广大，能保佑农耕、经商、旅行、婚姻，能疗病救人，尤其能使妇女生子，儿童无恙。故旧时妇女信仰碧霞元君特别虔诚，不仅在泰山有庙，在各地也建有许多“娘娘庙”，并常在左右配祀送子娘娘、催生娘娘、眼光娘娘、天花娘娘等四位娘娘。这种信仰至今仍很兴旺，人们仍不辞劳苦登上泰山绝顶，许愿还愿，向其祈祷，香火不断。
碧霞元君的圣诞为农历的四月十八日，一说农历的三月十五日，是时泰山碧霞祠和供奉碧霞元君的庙观均要举行隆重的庆典。
