God can be roughly divided into four categories: the first category is the most high god. In Shuo Wen Jie Zi, "God" is interpreted as: "God leads to all things." This is the original meaning of God. For example, Laozi, Sanqing, Yuanshi Tianzun, Jade Emperor and so on in Taoism. The second category is natural gods, such as sun gods, moon gods, mountain gods and Hebo. This should be a remnant of primitive worship. The third kind is the inner god. Taoism believes that all organs in the human body are under the control of God, such as the three-body god and the five-sense god. The fourth category is the largest number of gods, that is, ghosts and gods, which are usually recommended as gods by worshippers or believers after death, or officially canonized as gods.
Fairy words have just begun to become immortals. "Immortal" in Shuo Wen Jie Zi means: "Immortal has gone." Fairy means moving (moving) fairy is a later word, which is not found in Shuowen. The word "immortality" is explained in Ming Jie: "Old and immortal." Therefore, the immortal is usually the title obtained by the living after cultivation.
