According to Han Confucianism, the river map is Fuxi's gossip, and Luo Shu is Yu Hongfan's nine realms, which is the original theory of Han people. For example, "History of the Five Elements of Han Dynasty" says: "The river paints, Luo writes, and saints write." Liu Xin thought that Fu was the queen of heaven and was influenced by the river map, so he drew it, and the gossip was also true. Yu treated the flood and gave Luo Shu, which was obtained from the law, and Hong Fan also gave it. "Little imagine, this is not the case!

According to the historical records of the Book of Changes, the two paintings, Hetu and Luoshu, were only black and white in the Song Dynasty. My textual research:

1. The prototype of the black-and-white image of the river map is Guanzi Juvenile Official Map and Taixuanxuan Map, which originated from the number of five elements (heaven and earth) in the Han Dynasty.

The juvenile official map is the title of the ninth article of Guanzi. The order of drawing is western painting, western painting, Nanyang painting, Chinese painting, northern painting, Nanyang painting, Chinese painting, northern painting, oriental painting and oriental painting. According to the painting order and characters in the description of the Young Official Map, combined with the five elements of Shangshu Hongfan, it coincides with the river map of Song Confucianism, so the prototype of the river map is the Management of the Young Official Map.

Taixuan is a famous book of Yi studies written by Yang Xiong in the Western Han Dynasty. Xuantu originated from Youguantu, which is a combination of five elements in Xuanshu.

The eighth Xuan book in Tai Xuan Juan says, "March 8th is wood, east is spring … April 9th is gold, west is autumn … February 27th is fire, south is summer … January 16th is water, north is winter … May 5th is earth, middle is four-dimensional".

The 10th Mystery Map of Taixuan Volume, which is derived from the numbers generated by the five elements, says: "One and six sects, two and seven * * * friends, three and eighty percent friends, four and nine, five and five."

The generated number of the five elements refers to one, two, three, four, five, six, seven, eight, nine and ten. One, two, three, four and five respectively represent the five elements-water, fire, wood, gold and earth, which originated from the cloud in the book Hong Fan: "Five elements: water, fire, wood, gold and earth." Because soil is the mother of all things, every life plus five becomes their own so-called number.

The number of students is one to five, which symbolizes the occurrence of things; Numbers from six to ten represent the formation of things. The number of five elements is also called the number of heaven and earth.

The Book of Changes says: "There is one place and two places in heaven, three places and four places, five places and six places, seven places and eight places, and nine places and ten places. Five days, five digits, five combinations. Five in twenty days, thirty in places and fifty in places. "

Zheng Xuan in the Eastern Han Dynasty noted: "Born in the north water, born in the south fire, born in the east wood, born in the west gold, born in the middle. Yang is not even, Yin is not matched, and the two are not complementary. 60% of the land is in the north, which is in harmony with the sky (the sky is full of water and the land is 60%); 70% of fires in the south are combined with two places (two places make fires, 70% a day); Eighty percent of the land is in the east, which is in harmony with the sky (the sky is three trees, and the land is 80%); Jin Jiu in the west, and four places together (four real estate gold, Jin Jiu in the day); 100% in China, and Tianhe. "

The so-called five elements are born into numbers, but the ancient Tessa people try to explain the relationship and change between heaven and earth, yin and yang, and parity. According to the fact that the sky is yang, the earth is yin, the odd number is yang and the even number is yin, the result of this addition is that each line of the five elements has a birth number and a number match, that is, the odd number (yang) and the even number (yin) match, forming a pair of yin and yang hidden from each other to show that water has yang water and yin water, fire has yang fire and yin fire, and wood has yang wood and yin.

Young Official Map and Xuantu are both Notes on Heaven and Earth by Zheng Xuan in the Eastern Han Dynasty, and their theories existed as early as Taixuan in the early Han Dynasty.

2. At present, the popular black-and-white images of Luoshu originated from Zheng Xuan's annotation of "Nine Palaces in Taixia" in Yi Ganwei's Letters before the Eastern Han Dynasty, which was called "Nine Palaces" in the Han Dynasty.

Jiugong originated from the theory of "Nine Rooms" in "Da Dai Ji Li Ming Tang" in the early Western Han Dynasty.

The number of "nine palaces" indicates the changes of cold, heat and yin and yang at four o'clock and one day. This is related to Meng Xi and Jing Fang's theory of divinatory symbols in the Western Han Dynasty.

One, three, five, seven and nine are odd numbers, also called yang numbers; Two, four, six and eight are even numbers, also called negative numbers.

Yang number is dominant, ranking four positive (east, south, west and north), representing the weather; Yin number as the supplement, in the four corners (southeast, southwest, northeast, northwest); Among the five houses, one, three, seven and nine are rustic, and the ancestor of the five elements is located in the middle palace and flourishing in all directions.

The number indicates the change of cold and temperature in the four seasons, and the intensity of light and heat day and night. Among them, the odd number is Yang, which represents the temperature and luminosity changes of spring, summer, autumn and winter and day, night, morning and dusk. For example, three represents the temperature in spring, nine represents the heat in summer, seven represents the coolness in autumn and one represents the coldness in winter; The third is dawn. In the morning, the light is getting stronger; Nine is the middle of the noon sun, so light and heat are the strongest; Seventh, in the afternoon, the sun goes down in the west, and the light and heat gradually weaken; First, at night, light and heat are the weakest. Located in the north, No.1 is the cathode of a year and the solstice of winter; Nine numbers are in the south, which is the anode of a year and the solstice of summer; From one to nine, yin disappears and yang grows, from cold to hot, from nine to one, yang disappears and yin grows, from hot to cold; There are three vernal equinoxes in the east and seven autumnal equinoxes in the west. This shows that the characters in Jiugong (Luoshu) represent the spatial orientation and time season, and also symbolize the heat and light intensity of the six gases in the four seasons.

In addition, the image of "Luo Shu" is consistent with Wang Wen's two first pictures of "The Eight Diagrams of the Day after Tomorrow" and "The Eight Winds of the Nine Palaces of the Soul".
