The Queen Mother of the West (西王母), known in English as Xi Wang Mu or Hsi Wang Mu, and in Japanese as Seiobo, is an ancient Chinese goddess, also known in Japan and Korea. Her origins can be traced back to oracle bone inscriptions of the fifteenth century BCE that record sacrifices to a "western mother".
Even though these inscriptions illustrate that she predates organized Taoism, she is most often associated with Taoism. From her name alone some of her most important characteristics are revealed: she is royal, female and is associated with the west. The growing popularity of the Queen Mother of the West, as well as the beliefs that she was the dispenser of prosperity, longevity, and eternal bliss took place during the second century BCE when the northern and western parts of China were able to be better known because of the opening of the Silk Routes.
According to the myths, Hsi Wang Mu gained immortality by nurturing her “yin essence” through the absorption of energy from her sex partners. “Every time she had had intercourse with a man, he would immediately fall ill, but her own face would remain smooth and transparent.” And as she had no husband, she preferred sex with young boys.
Referred by Hsi Wang Mu, the goddess lived on Mount K'un Lun and was known for gaining immortality by copulating three thousand men to death. She'd became a lover of the immortal Orlando (then known as Bio) in 960 BCE for the next 200 years. Two millennia later, Hsi Wang Mu was challenged, killed, and replaced by Ugandan immortal Ayesha in her stead of K'un Lun, now known as Fire Mountain.
