What's the matter with Laozi's gasification and Sanqing? Who are there in Sanqing?

During the Wei and Jin Dynasties, Taoist immortals were very complicated, but scattered and disorderly. During the Southern Liang Dynasty, Tao Hongjing, a famous Taoist theorist, began to appear as the first systematic Taoist spectrum. In this book, Tao Hongjing divided the immortals into seven grades, each with a middle position, presided over by a fairy, and there were several seats on the left and right sides except the middle position to arrange immortals. Seven grades are different, with the first grade as the highest, and the grades are orderly. In addition to the middle gods, there are different levels of gods, such as the first level, 29 gods on the left and 19 gods on the right. The third level has more than 50 gods on the left and more than 30 gods on the right. Some of these immortals are emperors, generals or sages in history, such as Confucius, Yan Hui and Zhuangzi in grade three, Qin Shihuang, Emperor Gaozu, Qi Huangong, Jin Wengong, Wei Wudi, Liu Bei, Li Guang, Han Sui, Sun Ce and Cao Cao in grade seven. Some are famous Taoist leaders, such as Wei, Xu Yong, the founder of Taoist Shangqing School, Xu Laile and Ge Xuan, the founder of Lingbao School, the originator of Taoism in the fourth order, and Ge Hong, a great Taoist theorist. Some of them are characters in myths and legends, such as Huangdi, Tang Yao, Yu Shun and Yu Xia in the third order, and Pinus densiflora in the fourth order. In a word, there are all kinds of characters in Shenpu, most of them are well-known figures, but there are also some unknown figures, which are difficult to verify, and some have little to do with Taoism, such as Confucius, which is neither fish nor fowl. In addition to the divine spectrum of Tao, there are various divine spectrums, and their structures and contents are also different.

The spectrum of Tao Hongjing's "Bitmap of True Spirit" is only the text of the Shangqing school. It regards Yuan Shen, Yuan Wang, Tai Shang Dao Wang and Jin Que Wang as the highest gods, Lingbao School regards Yuan Shen and Tai Shang Lao Jun as the highest gods, and Shi Tiandao respects Lao Zi as the highest gods. The three factions have their own ways, and they are not completely consistent on the issue of the most high god. With the development of Taoism and the blending of various schools, the unified supreme god "Sanqing" appeared at the end of the Northern and Southern Dynasties, namely, Yuanshi Tianzun, Lingbao Tianzun and Moral Tianzun. The appearance of Sanqing God marks the final finalization of Taoist immortal pedigree.
