05 days: It is military weather.

Heaven, yin and yang, cold and heat, time system also.

Cao Cao's note: "Because of the four seasons system of Yin and Yang, the punishment is in accordance with heaven. So Sima Fa said,' I don't want to be promoted in winter and summer, so I love the people.' "

Did Cao Cao himself abide by his own Shuntian "yin and yang cold and summer time system", and did not start a teacher in winter and summer?

And he lost a famous battle, that is, Battle of Red Cliffs. Just like the SWOT analysis made by Zhou Yu and Sun Quan when they were in the temple, this paper analyzes Cao Cao's disadvantages: "It's cold today, and there is no grass for the horse, driving away the gentry and traveling far and wide." If you are not used to water and soil, you will get sick. This is also a big taboo. " In the cold winter, horses have no forage to eat. Cao Cao and his northern army traveled all over the rivers and lakes. They are unaccustomed to the climate and are prone to catch the flu, which is a big taboo in fighting.

"Yin and Yang", "cold and summer" and "time system" are progressive relations. There are yin and yang in the sky, which rise and fall each other, forming cold and heat. Four points of cold and summer, forming spring, summer, autumn and winter, is the time system.

When a strategist talks about Heaven, it should be said that there are three meanings.

First, it is the general trend of the world, and it is suitable for people; Second, it is the so-called night astrology, looking at the clouds and looking at the gas, and the tortoise burns divination; The third is four o'clock in cold and summer, weather forecast, and using meteorological conditions to fight.

The first level is the overall situation and grand strategy, which was decided before sending troops.

The third layer, such as gale, severe cold, midsummer and heat mentioned in the Art of War by Wu Qi, is suitable for its interests and uses meteorology as a weapon to fight. For example, fire depends on the wind, and the wind depends on the sky.

The second floor says the most, but it's all propaganda for others. "To confuse fools", I never believe it. As Jiang Taigong said, "A wise man breaks the law and a fool is arrested."

Zhou Wuwang cut Zhou, and arranged in Sitou Mountain. On that day, the storm, flags and drums were blown down and destroyed. The guards on King Wu's chariot were scared to death. Jiang Taigong said: "Those who use troops may not be lucky if they obey the Heaven, and those who go against the Heaven may not be fierce. If they lose their personnel, the three armies will be defeated. Moreover, the gods and ghosts in heaven turned a blind eye and turned a deaf ear to this, so the wise broke the law and the fools were arrested. Today, when a good man can do something, when he gets it, he doesn't look at time and interests. He does good without false divination, and he is blessed without waiting for the temple. " So he ordered the troops to move forward.

Duke Zhou objected, saying, "At this time, the turtle is burning fiercely, and the prophecy is ominous and the star is fierce. Please go back to the teacher. "

Jiang Taigong was furious and said, "Why not kill Ji Zi and Fei Lian?" Dry grass and rotten wood, an encore tiger? "

Jiang Taigong called the divination sign hay and the unlucky tortoise back rotten bones, and called for them to be burned. He led his own team first, and the prince of Wu followed suit and destroyed it.

Liu's Murong Chao is in Optics Valley, and he intends to attack the city. Generals turn to the yellow calendar. The day of "death" was unlucky, and everyone said, "I can't go!" Emperor Wu of Song said, "If you die, you will die. Good luck, good luck, good luck. " So he captured the optical valley.

So people in China say that climate, geographical location, people and harmony, and climate is mainly people and harmony. The harmony of mankind is the harmony of our own people. The weather is the sum of all the people in the world.

The days of military strategists are military weather. As for watching stars, clouds, gas, divination and burning turtle backs, they are all propaganda work, and politicians are never superstitious.
