Is Taiyi a real person, the Buddha who saved the suffering from Taiyi?

No, many people think that Taiyi Zhenren and Taiyi Salvation Buddha are the same person, but they are not the same person.

Emperor Tsinghua of Dongji, also known as Taiyi, one of the Nine Emperors in Heaven, is also known as "Seeking Sound to Save the Painful Heaven", "Taiyi to Save the Painful Heaven" and "The Nine Yang God in the Qing Dynasty".

Taiyi's rescue of the suffering Buddha and the Antarctic true Wang Yuqing are both attendants of the Jade Emperor. He is the incarnation of Yu Qingying, that is to say, Yun Qi is the incarnation of Yu Qingying in The Secret Records of Jiuyang Essentials. In Taoism, there is another way to govern hell, that is, Emperor Wei Zi incarnates the ghost Fengdu Emperor, the God and Lord of Taiyi.

Taiyi, a real person, is a virtual character in the novel Romance of the Gods and the storytelling "Immortals Break the Sky". He was a disciple of the Buddha in the early Yuan Dynasty, and Twelve Jinxian in Kunlun ranked fifth. He practiced in Jinguang Cave in Qianyuan Mountain. It is clearly mentioned in the Romance of Gods that Taiyi is the "founder of Wei Qing". Wei Qing School is one of the three schools of Fu You in the Southern Song Dynasty, which lasted from the end of Yuan Dynasty to the beginning of Ming Dynasty.

Detailed description:

Taiyi Zhenren and Taiyi Shenzun have similar names, but there are not many similarities in other aspects. Taiyi is a fictional character in the Romance of Gods, and Taiyi is a serious Taoist deity, which is directly quoted in The Journey to the West. "Romance of Gods" should be the author's re-creation based on Taoist mythological figures, and the two cannot be simply linked.
