Which of the three immortals, Taishang, Taibai and Taiyi, is the most powerful?

Laozi, the old gentleman on the throne, is considered to be the ancestor of Taoism. Lao Tzu's surname is Li Minger, the word Bo Yang, also known as Zhong Er (dān). He was a native of Qurenli, an ancient county of Chu (near Lu Yi today) in the Spring and Autumn Period. He once worked as a Tibetan shepherd in the Zhou Dynasty and wrote the Tao Te Ching. His "inaction" philosophy can be said to have a far-reaching impact on China's later generations.

In the Taoist myth system, Laozi is the eighteenth member (or incarnation) of Laozi. According to legend, Laozi was born at the beginning of the Emperor (Pangu itself is a descendant of Pangu, which can be considered as the primitive man of God). He is familiar with the principles of nature and the methods of educating immortals. He is the teacher of all the immortals in the celestial world. Laozi is invisible, but he is everywhere. He has no substance, so most people can't understand him.

He first ordered the mysterious jade girl to descend to earth and become the daughter of the Yin family in Tianshui. Later, she was born in the womb of a mysterious jade girl from Taiqing Wonderland. The place where she lives is quiet and peaceful, and evil has not invaded. Even in winter, there is no ice, and there is no heat in summer. Auspicious light often appears. Even the five elements of animals were guarded in front of the hall, so she was pregnant for 80 years, while the mysterious jade girl remained young forever.
