Zu Chongzhi once said in his works that he began to "specialize in mathematics and search for the past and the present" from a very young age. He collected almost all documents, records and materials from ancient times to the present.

At the same time, it is advocated that we should never "falsely push the ancients", never tie ourselves to the outdated wrong conclusions of the ancients, and make accurate measurements and careful calculations in person. As he himself said, he often "looks at the ruler, looks at the instrument and tries his best to make plans."

I am willing to listen to the evidence to verify the facts. The rhetoric is empty and derogatory, and stealing is not afraid of anything.

In 462 (the sixth year of the Southern Song Dynasty and the Ming Dynasty), Zu Chongzhi presented the carefully compiled Da Li Ming to Emperor Xiaowu of Song Dynasty for promulgation and implementation. Emperor Xiaowu of Song ordered officials familiar with the calendar to discuss the advantages and disadvantages of this calendar. During the discussion, Zu Chongzhi was opposed by Dai Faxing, and Zu Chongzhi refuted it in the article Yi Lee.

In Li Yi, he wrote two famous sayings: "I am willing to listen and give evidence, I am willing to check the facts" and "I am afraid of stealing words." In order to distinguish right from wrong, he is willing to produce obvious evidence to discuss with the other party, and he is not afraid of those unfounded accusations.

3, not a genie, tangible and detectable, there are a few to push.

Dai Faxing believes that the way to continue the tradition in the calendar is "the ancient man-made chapter", "the world is not easy"; He called Zu Chongzhi "false chanting" and thought that the astronomical calendar was "too numerous for people to measure" and "you should not make mistakes lightly". Zu Chongzhi defy spirit.

He retorted that we should not "believe in the past and doubt the present". If "the ancient method is sparse, it should be commonly used", what is the truth! The movement of the sun, the moon and the five stars is "non-supernatural, tangible and measurable". As long as accurate observation and research are carried out, Mencius said that "it is possible to sit at the age of chitose".

Character evaluation:

1, Hua (from Zu Chongzhi's Pi): "Zu Chongzhi is not only a mathematician, but also familiar with astronomical calendars, mechanical manufacturing, music, and a writer. Zu Chongzhi's Daming Calendar reformed the calendar. He calculated pi to seven decimal places, which was the most accurate value in the world at that time, and his "secret rate" was world-famous. "

2. History of the South: The understanding of Baise in Lv Zhong was unique at that time and could not be right.

3. People's Network: Zu Chongzhi and his son's achievements in mathematical research are included in his mathematical monograph "Composition". This book is so profound that "scholars can't study its profundity, so they ignore it." In the official school of the Tang Dynasty, Zhuanshu was also listed as one of the top ten required books, and the study time was four years, with the number of years being the first of all books.

Later, seal script spread to North Korea, but after 10 century, seal script was gradually lost in various countries. Although we don't know the specific content of Zhuanshu today, we can still imagine its academic value from the research years of the book by the official schools in Tang Dynasty and the related sporadic records in the history books.
