The legendary river map is two mysterious patterns handed down from ancient China. "River Map" was made by a beast named "Malone" on the Yellow River in the ancient Fuxi period. Fu painted gossip on this basis. "Luo Shu" is a pattern on the back of a turtle in Luohe when Dayu wrote Hong Fan.
Therefore, Hetu Road is considered to contain the principle of heaven and earth and is one of the sources of Chinese civilization.
I mainly read Luo Shu today. The common black and white dot "falling book" is as shown above. The white dots in the figure represent positive numbers, that is, odd numbers. Black dots represent negative numbers and even numbers.
Let's change this number. Odd numbers on the periphery and even numbers on the inner circle are still centered on 5, as shown in the following figure:
In fact, this number is still a "falling number". Only black and white dots are represented by numbers, and then even and odd numbers are divided into inner and outer circles. At this time, we found a magical "multiplication cycle phenomenon" in the figure, specifically:
Look at the odd numbers on the periphery first:
Multiplying one equals one, and the cycle is in place.
Three times three equals nine, and nine is a number. Nine times three equals twenty-seven to seven; Seven times three equals twenty-one plus one. One times three equals three. Count three times. Rotate the periphery clockwise once, and then rotate it back three times. And continue to repeat the cycle.
Seven times seven equals forty-nine and the result is nine. Nine times seven equals sixty-three and you get three. Multiply three by seven and twenty-one to get a number. Seven times seven equals seven, and seven counts. Turn the periphery counterclockwise and return to the 7 o'clock position. And continue to repeat the cycle.
Nine times nine equals 8 1, count as one. One times nine equals nine, and nine counts. Cycle back and forth between one and nine o'clock.
Let's look at the even number of the inner ring again. The same phenomenon is true:
Two times two plus four equals four. Four times two plus eight equals eight. Eight times two plus sixteen equals six. Six times two, twelve equals two. The inner ring rotates counterclockwise once and goes back twice. And continue to repeat the cycle.
Four times four equals sixteen, which equals six. Six times four equals twenty-four plus four. Cycle back and forth between four and six.
Six times six equals thirty-six. This is the number of six, and the cycle is in place.
Eight times eight equals sixty-four, four. Eight times four equals 32, and you get two. Two times eight equals sixteen, and six is a number. Six times eight equals forty-eight plus eight. Turn the inner ring clockwise once and return to eight turns. And continue to repeat the cycle.
Central: Five times five equals twenty-five to five. The loop is in place.
That is, starting from a specific number, taking this number as a multiplier and multiplying it by the product of this number; The product multiplied by that number. If this continues, it will definitely return to that number. Some circulate in the same place, some circulate back and forth between two numbers, and some return to the original place after four steps.
In addition, the odd number on the circumference and the even number on the inner circle are: local cycle, round-trip cycle, clockwise four-step cycle and counterclockwise four-step cycle respectively.
Friends who know the river map may have seen it. This is the number of "River Map": 166, 27, 38, 49.
There should be some kind of mathematical theory in it. Can experts prove this?
