First of all, mathematicians
What we know most about Zu Chongzhi is pi. When he was studying mathematics, his greatest contribution was to put pi in the seventh place, which was a very important discovery at that time, and no one broke this achievement at that time. This research had a great influence in China at that time and even in the world. Even now, pi is widely used. However, he didn't just pay attention to pi. In the end, all his findings were written into his composition.
Second, astronomers
Zu Chongzhi has also made great achievements in astronomy. A book named "Da Li Ming" records his great achievements in astronomy. Through his own calculation, he found that there was no small error in the previous calendar, so he compiled the Daming Calendar and introduced the latest calendar he calculated. Unfortunately, it was not widely used in later generations.
Third, the writer
Zu Chongzhi described some things about ghosts in Strange Tales from a Lonely Studio, which attracted many readers. Many later writers learned from him and learned his writing style, which caused a wave of enthusiasm. His books are widely circulated in the society and are loved by many people.
