The Milky Way is on the left, and the solar system is also on the left, and the planets are on the left, and the rotation is on the left...

Even the human body's qi and DNA are all rotating left.

The magnetic field generated by the current is also left-handed.

This can no longer be explained by coincidence. When all facts are placed before us, it is the truth, which is as the old master said - the way of the Tao is left-handed.

"When I knew the way left, wasn't I wondering again when I looked at the Tai Chi diagram?"

"The Tai Chi diagram drawn by using the guibei is right-handed, but the Tai Chi diagram you usually see is used in the Taoist world, right?"

“This is actually a matter of perspective.”

"Look, when we look at the starry sky, it is actually mirror-like."

"Tai Chi comes from the sky after all, so when you turn it over, the left-handed Tai Chi diagram is the original form of the way of heaven."

"Although the Tai Chi diagram was drawn based on the guibei, it was this kind of 'heavenly drooping elephant' that reflected the great way. The ancestors' understanding of the world rose from the superficial elephant to the Tao."

"It would be very simple to reason with the Tao."

"Your father didn't tell you where the Yin-Yang fish in the Tai Chi diagram came from. He wanted me to tell you the connection between practice, but in fact, if you want to preach, you will still start from the image level."

"Your father talks about the guibei and shadow measurement, and he should tell you that our planet actually revolves around the sun, right?"

Zhang Zhixiang nodded and thought to herself, it turns out that everyone knows...

Soon, he was shocked that this recognition was not the result of Zheng He's fleet's global navigation surveying and mapping, but was known to his ancestors thousands of years ago.

The old master asked: "So do you think, from our perspective, how do the sun and the moon move?"

Zhang Zhixiang raised his hands blankly. If one hand is the sun and the other hand is the moon, then their movements around me will be like the Yin and Yang fish in the Tai Chi diagram, just the speed of both...

"Senior brother, they have different speeds."

The old master asked back: "Does the day and night equally long? Are yin and yang clear? How can the rotation of the moon have nothing to do with the sun? What is the difference between turning one circle and turning twelve circles?"

"If it is just a slight subdivision, you will not be able to learn yin and yang."

"Yin and Yang are unified."

"Do you understand?"

Zhang Zhixiang was a little ignorant, mainly because he had some conflicts with his previous life's cognition, but he could understand the meaning of his senior brother. Although Yin and Yang are divided into Yin and Yang, they are actually one.

The motion of the moon is affected by the gravity of the sun, so the rotation rate of the two is actually the same after taking into account these effects...

"I don't think it's verified, right?"

Seeing Zhang Zhixiang like this, the old master was not impatient, but was very interested and said: "Mathematics originated from astronomy. In Qin Jiushao's "Nine Chapters of the Numbers", there are statements about internal calculations and external calculations."

"The words: Those who are related to the square and round are Chi's techniques, which are all called external calculations, and are internal. Their uses are consistent and cannot be different."

"Internal calculations and external calculations are actually the same. What you see and know is how tall this building is, how long the shadow is, and how heavy the objects are. These are all external calculations. External calculations can be seen intuitively, so the concept of external calculation theory will be born."

"In fact, everything interferes with each other."

"The verified persons in the external computing institute can only be correct under a certain scale."

"If the scale is not controlled, it will not work. Today's external calculation method cannot calculate yin and yang. This is normal. After all, it is a deduction of the great way. There are endless descendants and endless calculations."

"I heard that Wang Wensu of Shanxi completed the book "Mathematical Learning Treasures" and made some progress in calculations. But at present, it is still far from enough."

"Maybe one day in the future, if you calculate it to a certain level, you can deduce it."

"Before that, we should use internal calculations to observe the world and the Tao."

"The most widely used internal calculation is divination, mainly: Taiyi, Liuren, Sanjia, and of course, these are all magical paths. If you learn it in the future, we will continue to learn the great path now."

There is actually these contents in "Nine Chapters of the Numbers"?

Zhang Zhixiang knew Qin Jiushao, a master of mathematics, but he did not expect that ancient mathematics was so developed...

"When it comes to the calculation of yin and yang, not only is it difficult to deduce external calculations, but also internal calculations are difficult to deduce. Therefore, it is necessary to divide Tai Chi into two yin, two yin into four symbols, and four symbols into eight trigrams, so the five elements are needed."

"Since you want to tell Tai Chi, you can't avoid a story."

"Kuafu chases the sun."

"The "Shan Hai Jing" records: Kuafu and the Sun are rushing away, and they enter the Sun. They want to drink, and drink in the river and Wei. The river and Wei are not enough, and drink in the north. Before they arrive, they die when they die of thirst. They abandon their staff and turn into Denglin."

"Kuafu and Sun Zhui are indeed chasing the sun."

"Because Kuafu recorded the changes in the sun shadow during the year at different locations, so as to measure the sun time, the method of measuring the sun shadow is to measure the sun shadow."

"He first measured the Yellow River and Wei River Basin, but found that it was not enough, so he went to the 'north'."

"This north is the extreme north of the sun."

"This is an area where the sun shadow is zero during the summer solstice."

"so."

"Beiyin Daze is heading towards the Yangtze River, but before the Yangtze River is measured, Kuafu died. The wooden pole he used to measure the sun shadow is peach wood, so we say that peach wood is pure yang wood and has the effect of warding off evil spirits."

"So where did Kuafu finally arrive?"

"It's Han River."

"Kuafu is not only measuring the shadow of the sun, but also mapping the geography along the way. It is also the continuous survey and mapping records of our ancestors that we have passed down the mountain and sea classics."

"After he mapped the shape of the Han River, he accidentally saw the Milky Way while thinking about the laws of astronomicality at night."

"The shape of the Milky Way is so similar to the Han River."

"So, name it Hanjiang."

"What is Han?"

"Why are we Han people? Not Qin people? Not Zhou people? Because there is Han people in Weitian! Stars and Han people are brilliant, this is our Han people!"

"The sky hangs the elephant, and the saints take it and determine the name of the Han Dynasty."

"And using the gui table to measure the length of the sun shadows of the four seasons, we get the Tai Chi diagram, and determine the two-part two-way arrival, and determine the four seasons of hunting. Kuafu is the father of China, so he named him "father."

"What is China?"

"The country of the central government is the country of Suming." (The oracle bone inscription with the character "Zhong" is a pictographic character for the guibian shadow measurement. China refers to both the country of the central government and a country that understands the way of heaven, so we call the Heavenly Dynasty not actually arrogant.)

"First Suiren observed the Great Mars, and he set the 'year' and had the effect of opening the sky."

"Therefore, the Suiren was respected as the emperor, and there was the Shuming Kingdom. Kuafu was a native of Shuming Kingdom. Because Kuafu passed the sun and obtained the four-season calendar, the Shuming Kingdom became the central country until Fuxi inherited the Shuming and Huaxu Kingdom, and was the common ruler of the world, and was called China."

"There is a painting of Xihuang who opens the sky, derives Tai Chi, produces the five elements, and determines the Eight Trigrams."

"From then on, the great way will be settled."

Zhang Zhixiang was shocked and stunned. It turned out that this is how the Chinese and Han people came from.

To learn Taoism, we must first figure out where we came from, and understand how our civilization evolved to this point, and how the Yin and Yang, Five Elements, and Eight Trigrams were obtained.

After letting Zhang Zhixiang digest it for a while, the old master pointed to the Beidou in the sky and said.

"The handle of the Dou east refers to the spring of the world; the handle of the Dou south refers to the summer of the world; the handle of the Dou west refers to the autumn of the world; the handle of the Dou north refers to the winter of the world."

"To observe the sky, you must first observe the Beidou."

"The Beidou is the pointer, the Zhoutian is the dial, and there are twenty-eight scales."

"The seven constellations of the eastern Qinglong are: Jiao, Kang, Di, Fang, Xin, Wei, Ji; the seven constellations of the northern Xuanwu are: Dou, Niu, Nu, Xu, Wei, Shi, and Bi; the seven constellations of the western white tiger are: Kui, Lou, Zhou, Mao, Bi, Wei, and Shen; the seven constellations of the southern Zhuque are: Jing, Gui, Liu, Xing, Zhang, Yi, and Zhen."

"Look."

"The direction the handle of the bucket is now pointing, and there is the northern Xuanwu, just between the Xu and the Women."

"When is the winter solstice come and go? It is the hour of the middle, and the corresponding star is dangerous, empty, and female. After the middle, it is the hour of the ugly, and the corresponding star is the cow, and the Dou."

"We often say that qi rushes to bullfighting, which describes the sharp sword energy, because at this time the cold air between heaven and earth is the most intense, and when the handle of the fight turns around and sinks."

"The handle of the fight returns to Yin, the earth returns to spring, and at this time... it is the first of the year, the Spring Festival."

"Look..."

"It rises when it reaches the dragon's tail, and rotates left and goes up. The green dragon belongs to wood. In spring, the Vermilion Bird belongs to fire. In summer, the white tiger belongs to gold. In autumn, the Xuanwu belongs to water. In winter."

The old master stopped when he said this, Zhang Zhixiang murmured "wood, fire, metal and water". Why is there one missing in the five elements?

Four seasons and five elements.

Not worthy...

"Senior brother, even if the center belongs to earth, why do the other four elements have seasons, but earth does not?" In Zhang Zhixiang's concept, earth should be the most important of the five elements, and it should not be like this.

The old master smiled and said, "It was originally there, but now it is gone."

"In ancient times, October was used as the calendar, and the year was divided into five seasons, spring, summer, long summer, autumn, winter, and long summer were earth. Look, wood produces fire, fire produces earth, earth produces metal, metal produces water, and the five elements are generated, which comes in the order of the five seasons."

What was the 10th month calendar in ancient times?

Zhang Zhixiang was a little confused. He couldn't understand ancient history and could not learn Taoism.

"But why did it still turn into four seasons?"

He is not arguing, he really doesn't understand that the images corresponding to the climate of the four seasons are very appropriate, and there is no situation in the year that can be used to correspond to the soil.
