One hole is seen --- reversal of black and white Su Xueba

Su Zirong passed the province and endowed him with "the calendar, the great age of heaven and earth", which was the leader of the field. Once he ascended to the top, he paid attention to the history. In Yuanfeng, the winter solstice will be met, and the day before the captivity calendar, the messenger will enter the congratulatory manner. Captives can't help but learn astronomy and mathematics, and they are often proficient. In fact, the Khitan calendar is positive, but it is unavoidable. Zirong is a general theory of history, and the evidence is detailed and knowledgeable, and the captives are unpredictable and sensational. That is, Xu said: "This is not enough to compare, but it is a moment away." In the middle of the night, one more moment is today, and one less moment is tomorrow. "The captives cannot be broken. Then from the return, Shenzong was overjoyed, that is, he asked: "What is the second calendar?" "Because of the truth, Taishi was punished.

-------I am the dividing line of Sindaya-------------

When Su Song (Zirong) participated in the provincial examination, he wrote an essay around the theme of "Calendar, the Great Age of Heaven and Earth", and won the provincial champion. After officially entering the cadre sequence, he was still very interested in the calendar, and he studied and accumulated on his own for a long time.

During the Yuanfeng period, Su Song sent an envoy to the Khitan, which happened to be the winter solstice, and asked the envoys to congratulate.

According to the Khitan calendar, the winter solstice is the day before the winter solstice in the calendar of this dynasty, in fact, this is correct, because the Khitan does not prohibit the folk from learning astronomical and mathematical knowledge, so there are many people who are proficient, but (although it is so), but they must not admit it!

So, Su Song began to tell them "since ancient times", widely quoted, used many, many ancient books and allusions, listed a large number of professional formulas and star and moon charts, and the Khitan people were dizzy and didn't understand what he was talking about.

At this time, Su Song smiled and said, there is no need to delve into this, your calendar is actually very right, it is just a little wrong, accumulated over a long period of time, so it is a little different, and it is only a momentary difference. If this moment is placed at zero o'clock, one more moment is today, one less moment is tomorrow, and now (such a thing that the winter solstice is one day away), which is the reason why you have a moment more error! The Khitans were stunned by him at that time, and they couldn't immediately refute him.

After coming back, Shenzong was very happy when he heard this, and asked, "Whose calendar is right?" "After Su Song reported truthfully, (Shenzong) punished the cadres in charge of the calendar work in this dynasty.

-------I have to say that the dividing line of the suit-------------

As for Su Song, the official luck is still good, he has presided over the work of the Ministry of Officials and the Criminal Department, and has also entered the cabinet. But his more famous achievement is in astronomy, he once organized the research and manufacture of a large number of astronomical instruments such as armillary spheres, which were used until the time of Jing Kangsha, when Bianjing fell, and these equipment also fell into the hands of the Jin people.

THE MATTER OF SU SONG IS ACTUALLY A TYPICAL EXAMPLE OF GIVING UP ACADEMIC PRINCIPLES FOR THE SAKE OF POLITICAL POSITIONS, CLOSING MY EYES AND TELLING NONSENSE, BLABLABLA, USING MY IDENTITY AS A SCHOLAR TO SUPPRESS THE CORRECT ACADEMIC SCHOOL, I REMEMBER THAT I HAVE ALWAYS HATED THIS KIND OF PERSON...... But why, this time, I just feel so good?
