Lao Mao continued Lin Xihui's words and said that the summary of gossip is "to deal with people and things, and to turn evil into good fortune", which was used as "Yin and Yang Theory" in ancient times, and the so-called gossip is the eight hexagrams, and gossip is actually the earliest text and a text symbol. After the gossip, it represents the culture of easy learning.

One of the most well-known origins of gossip is according to the record of "Taiping Yulan": "Fu Xi sits on the square altar and listens to the breath of the eight winds, which is to draw gossip." "Take"—" for the yang, take the "--" for the yin, and form the gossip: dry is the sky, kun is the earth, the earthquake is the thunder, the kan is the water, the gen is the mountain, the Xun is the wind, the separation is the fire, and the exchange is the ze, so as to resemble the feelings of all things. In "Saying Hexagrams", the gossip has been specifically distinguished: "Heaven and earth are positioned, mountains and rivers are ventilated, thunder and wind are thin, and water and fire do not shoot each other." ”

According to Chinese folklore, gossip originated from Fuxi, the head of the Three Emperors and Five Emperors, who began to draw gossip in Tianshui Hexagram Taishan, and opened the sky with a painting. Bagua represents the yin and yang system of things that change themselves, with "one" to represent yang, and "--" to represent yin, with these two symbols, according to the yin and yang changes of nature, they are combined in parallel to form eight different forms, which are called Bagua. According to legend, Fuxi painted gossip in Guatai Mountain, and later Tianshui in Gansu and Henan also had Fuxi painting hexagram platform. Hexagram Taishan, also known as the painting hexagram platform, is the place where Fuxi looks up at astronomy, looks down on geography, and begins to draw gossip, which is located at the northwest end of Sanyang River, which is now Weinan Town, Maiji District. These are historical records, so they cannot be regarded as legends.

The Fuxi clan appeared in the Taihao period. There are also the names of Mixi, Bao Xi, Kuxi, and Huangxi, and some say that Fuxi is Taiyao. It is the ancestor of human beings in Chinese myths and legends, he taught the people to make nets, engaged in fishing, hunting and animal husbandry, because he participated in and guided a large number of various social practice activities, according to legend, Fuxi and Nuwa are husband and wife. The Xinjiang Uygur Autonomous Region Museum and the stone room of the Wuliang Ancestral Hall in Jiaxiang County, Shandong Province all have portraits of Fuxi holding the rules and Nuwa holding the rules with a human head and a snake body and a tail. In "History of the Song Dynasty, Fang Ji Biography, Han Xianfu Biography", there is also "Fuxi's armillary sphere, measuring the height of the North Pole, measuring the length of the sun's shadow, determining the north, south, east and west, and stargazing is vast." "That's it.

There are also various theories about the form, method and location of Fuxi's gossip painting. "Supplement to the History of the Emperor Benji" has "the king of the Bao Xi clan in the world, looking up at the sky, looking down at the law on the ground, watching birds and beasts and the appropriateness of the earth, close to all things, so he began to gossip, with the virtue of the gods, with the love of all things"; "Hanshu Five Elements Chronicles" has "Fuxi's vision of the sky, love the river and draw it, gossip is also"; "Henan Mansion Chronicles" has "When Fuxi, Longma lost to the river, and Fuxi painted gossip." The above statements have one thing in common, that is, the "Bagua Map" of the Fuxi period was indeed painted by the Fuxi family.

There are also various interpretations of the "Bagua Diagram", and some people believe that the eight symbols of the "Bagua Diagram" are the eight hieroglyphs of heaven, earth, thunder, wind, water, fire, mountain, and ze, reflecting the eight natural phenomena. Some people associate Fuxi's "listening to the qi of the eight winds" and gossip with the eight directions, that is, Qian's south, Kun's north, Zhen's northeast, Xun's northwest, Kan's west, Li's east, Gen's northwest, and Dui's southeast. Some people also believe that the eight symbols of "Bagua" represent the eight seasons, and according to the interpretation of "Eight Winds" in the "Etymology", the seasons are presumed to be: "Guangmo is the winter solstice, the wind is the beginning of spring, the Ming Shu is the spring equinox, the Qingming is the beginning of summer, the scenery is the summer solstice, the cool breeze is the beginning of autumn, the Chang is the autumn equinox, and the Zhou is the beginning of winter." ”

Regardless of the point of view, it is believed that "Bagua" is a primitive hieroglyph, a primitive picture representing all things in heaven and earth. As for the legend that the Fuxi clan sometimes has a dragon that looks like a horse on the Yellow River, carrying the "river map", the legendary river map, later generations believe that it may be a kind of auspicious and evil charm.

The original hieroglyphs should also have originated from the original drawings. The various interpretations of gossip by later generations have not departed from the objective existence of natural phenomena and the preliminary understanding of human beings about it. From the perspective of maps as a tool for people to express geographical things and phenomena and a product of human social practice, Bagua should be the original map in ancient legends.

In the Song Dynasty, Shen Kuo invented the wisp hanging compass, which represents the twenty-four directions in addition to the eight heavenly stems and twelve earthly branches, as well as the four weis (Qian, Kun, Xun, Gen), and "Sinan" and "Di" are eight directions representing east, west, south, north, northeast, northwest, southeast, and southwest with eight trigrams, which illustrates the relationship between gossip and measurement directions. The philosophical volume of the Encyclopedia of China explains the eight trigrams, and there are "eight trigrams and Fu Xi's observations of astronomy, geography, animals and plants, and the human body, etc., imitate their shapes." This also proves that the Fuxi Bagua map is the earliest original map of China.

Lin Xihui interrupted the old cat's words at this time, saying that in the 739 Mystery Bureau where they were located, there were special personnel to study the gossip, using a scientific analogy, there are three lines in the gossip, "Qian, Kun, Zhen, Xun, Kan, Li, Gen, Dui" are divided into eight directions, symbolizing the eight properties and natural phenomena of "heaven, earth, thunder, wind, water, fire, mountain, and Ze", symbolizing the changes and cycles of the world, and the classification method is like the five elements, everything in the world can be classified into the gossip, and the changes are endless. This can be seen as the ancestor of binary electronic computers.

And the stone statues we see now and the "nests" that appear on the ground, these are the subdivisions of the "gossip" of Qian, Kun, Zhen, Xun, Kan, Li, Gen, and Dui, that is to say, the stone statues we see now and the nests that appear on the ground can even deduce the origin of "gossip".

The bald head asked Lin Xihui, "Miss Lin has said so much, what are the stone statues and caves here for?" ”

Lin Xihui immediately replied, just like she just said, we can take the "Qian, Kun, Zhen, Xun, Kan, Li, Gen, Dui" of Bagua as the basis of binary, combined with the details of the "Bagua" that Lao Mao just said, to put it simply, the arrangement of stone statues here, as well as the nest on the ground, is now not just a certain feng shui layout. It's about recording or expressing something.

As for what it means, Lin Xihui shook his head, if anyone can know what is recorded here, I'm afraid there will only be Fu Yi.

After Lin Xihui finished speaking, the old cat nodded silently, and then said simply, "Fuyi is the Taihao period, if you follow the legend, these stone statues we see now and so on, may appear earlier than the Taihao period." ”

"Earlier than the Taihao period, what period would it be?" I muttered under my breath.

"The Age of Mythology." The old cat replied.
