Why is The Classic of Mountains and Seas a scientific book, as well as a book of witchcraft and mythology?

As soon as the class appeared, manual labor and mental labor formed the initial division of labor, and it was the wizard who mastered culture. Witches are equivalent to intellectuals in society and have a high status. "Guoyu Chu Yu" said: "The ancients, people and gods were not mixed ... their knowledge can be compared with righteousness, their sacred power can be far and wide, their brilliance can shine, and their intelligence can be heard thoroughly. If there is wisdom, there are surprises among men and witches among women. " Wizards were the cultural stratum at that time, and they were the "messengers" who communicated with heaven and earth. The original divination, calendar, medicine and sacrifice were all managed by wizards. "Literature, history, stars and calendars are almost between divination and blessing." At that time, "witchcraft, divination, divination and history" were integrated. In order to sacrifice, witchcraft and divination must be familiar with the names of mountains and rivers, and understand mountain gods and local products and specialties. They must have extensive knowledge of geography and natural history to participate in national celebrations, sacrifices and decision-making activities. The ancient sacrificial activities were very large in scale, and there were very valuable treasures in the sacrifices, which were managed by witches. In a word, the social status of ancient witches is important. They have a large number and a fine division of labor, and are familiar with myths, sacrifices, divination, dance, geography, natural history, medicine and so on. Shan Hai Jing is a wizard's book recorded according to ancient legends, which is a reference for them to practice witchcraft, and also records many ancient insights.
