Zhao Da-Zhao Da, a native of Henan (now Luoyang, Henan), was an alchemist in Wu Dong during the Three Kingdoms period. He studied with Fu Shan, a servant of the Han Dynasty, and was devoted and meticulous. He thought that there was a sign of an emperor in the southeast, so he left his hometown and crossed the Yangtze River. He studied arithmetic numbers in the Nine Palaces and explored the subtle truth, so he always worked out good or bad luck on the spot and gave a godlike answer, thus counting the number of migratory locusts and guessing the hidden items. Someone said to him, "The number of migratory locusts is incalculable. Who knows how many? I'm afraid this figure is a wild guess. " Zhao Da asked the man to sprinkle several buckets of adzuki beans on his seat. Zhao Da can immediately infer the number of beans, which is proved to be true. Zhao Da once visited an old friend he knew, and the old friend prepared food for him. After dinner, his old friend said to him, "What if there is no wine and no good food in a hurry?" Zhao Da picked up a chopstick on the plate, put it horizontally and vertically for two or three times, and said, "You have a bottle of good wine hidden under the east wall, and three catties of venison. How can you say no? " There were other guests present. Knowing the truth of the host, the host said with shame, "Because you are good at guessing whether there is anything, I want to try you." It is so effective. " So we took out the wine and drank it together. Someone wrote tens of thousands of numbers on the letter, put them in an empty warehouse and sealed them so that Zhao Da could calculate these numbers. Zhao Da speculated that the number was the same as the number on the letter and said, "Although these numbers exist, they are nominal." His calculation is so precise and subtle.

Zhao Da attaches great importance to his own skills, such as Kan Ze and Li Yin, who are both prestigious bachelor of Confucianism. They condescended to study at home in person, and Zhao Da kept a secret from them. Taishicheng Gongsun Tengnian worshipped Zhao Da as a teacher when he was young, and studied hard for many years. Zhao Da promised to give him skills for several years, but when he wanted to teach, he always stopped talking. One day, with wine and food, GongSunTeng observed Zhao Da's face and knelt down to ask Zhao Da to teach him. Zhao Da said, "My grandparents got this magical number to become the emperor's teacher. He has been an official for three generations, but he is just a Taishilang. I really don't want to teach anymore. And this set of tricks is subtle and profound, with multiplication at the beginning and division at the end. It is a method of liquidation, that is, the relationship between father and son does not tell secrets. But because of your tireless study, now I really want to teach you the secret of tricks. " After drinking several rounds, Zhao Da got up and took out two rolls of silk, which were as thick as fingers. Zhao Da said, "If you copy this book, you will understand all this. I have shelved this book for a long time and haven't read it. Now I want to think about it and give it to you in a few days. " Gong went as scheduled. When he arrived, Zhao Da pretended to look for the silk book, then exclaimed that it was lost and said, "My son-in-law came yesterday. He must have stolen it." So the relationship between the two people was cut off.

At first, when Sun Quan sent troops to conquer, he asked Zhao Da to do some calculations every time, and the results were the same as what he said. Sun Quan asked him about the secret of technology, but he didn't say anything, so he was alienated by Sun Quan, and neither Li Lu nor the official position got what he wanted. Zhao Da often laughs at those who do divination calculations, and says, "You should go back to the Chamber of Secrets and do calculations. You can know god's will without going out. Instead, you stand outside day and night to observe the weather signs. Is it too difficult? " Zhao Da had nothing to do, so he calculated himself with his own skills and said with a sigh, "I calculated that my life limit is a certain day of the month, and then I will die." Zhao Da's wife saw many times that Zhao Da's speculation was very effective. When she heard this, she began to cry. Zhao Da wanted to stop his wife's grief, so he recalculated and said, "I miscalculated before, and my death has not yet arrived!" " Later, he died as scheduled. When Sun Quan heard that Zhao Da had a book, he sent someone to ask for it, but he didn't get it. He interrogated his daughter until he found his coffin and Zhao Da's Jiugong was lost.
