In ancient times, there was "Tai Chi Map", because when Tai Chi was easy to occur, two instruments were born, and there were clearly two instruments running between the sun and the moon, which were the hanging of yin and yang, just like heaven and earth, one was clear and one was turbid. The sun and the moon are divided into yin and yang. The ancestors saw the sun and the moon rise and fall, one bright and one dark, alternating day and night, and the day and night became a moon, and the moon became an adult. Therefore, the theory of Yin and Yang is the same as that of male and female reproduction. Associating and confirming everything in the world. So there were River Map and Luo Shu. Biography of Shangshu Gu Ming Kong Anguo: "Fuxi is the king of the world, and the dragon and the horse are out of the river, so the river map is called' River Map' and' Luoshu' by drawing eight diagrams." "Han Li Wen Jia": "Fuxi and the world are one, and it is appropriate for heaven to write about birds and beasts, and it is appropriate for the land to write about He Tuluo, so it is appropriate to make changes." From this we know that the predecessors of gossip are He Tu and Luo Shu. The so-called river map is based on the ancient Taiji map, and the number of heaven and earth is determined to be fifty to five. The sun is due south and the moon is due north of the sky; Japan and China are due north, and the moon is due south. The number of days (yang number) is twenty-five, due north begins at midnight on the first birthday, due east is longer than the second birthday, and the seventh birthday is full at noon, so it is not used because of the lack of Secondary Five. When the number seven is full outside the birth number. When the sun shines, it is cloudy, so there are even positions (30), starting from the birth number two at noon due south, four times longer than the birth number at sunset due west, and full of six. Because six is a number, it should be midnight outside the birth number. Looking at the river map, we can know the number of students, from which mathematics is born, and there are generated figures. Number of students, one, two, three, four, five; The number came out, 24680. In the river view map, it is known that several generations have a moving direction, and the yang number starts from Yin Sheng in the north and ends clockwise in the west from east to south. The negative sign starts in the north and ends clockwise from west to north. The orbit of the sun and the moon is also the route of yin and yang, which can be described as a wonderful combination of gossip and nature. It can also be seen from the river map that the map is also a number generated by the five elements, from which geography and meteorology are born. From sunrise, from east to left, from east to south, fire is made from earth, from south to middle, from middle to west, from west to north, water is golden, and from north to east, aquatic wood is born. Ancestors believe that the number of river maps is mainly based on the number of students, and the number of students is unified into numbers. 1, 2, 3, 4, 5 students live inside, 6, 7, 8, 9 live outside, the middle is the main, and the outside is the guest. Its orientation: north 16 is water, south 27 is fire, east 38 is wood, west 49 is gold, and middle 50 is earth. It reflects the process of the consistency of yin and yang and five elements of qi throughout the year.
