Who is Liu Hong? What does it mean to be sacred?

He was a famous mathematician and astronomer in the Eastern Han Dynasty.

Abacus is a tool for performing calculations with an abacus. The invention of abacus has made a leap forward in people's computing ability, and the term "abacus" was first seen in the book "Mathematical Notes" written by Xu Yue, a native of the Eastern Han Dynasty and Wei Dynasty. Xu Yue said in the book:

Liu Huiji is erudite and well-informed, biased towards mathematics ......There are still many kinds of articulation, one of which is abacus. "The Liu Huiji that Xu Yue said is Liu Hong.

Some people say that Mengyin is the hometown of abacus, and Liu Hong is the father of abacus and is respected as a "saint of abacus". Abacus is one of China's five great inventions.

The famous mathematician of the Eastern Han Dynasty, who wrote "Nine Chapters of Arithmetic", is known as the "Sage of Arithmetic", because mathematics is called arithmetic in ancient China, using abacus as a tool, and Liu Hong can be said to be the father of abacus.

I suggest you take a look at this.

Liu? Why haven't you heard of it, oh the landlord, I'm lonely, but I personally think Zu Chongzhi should be considered a saint (and...).Although I hate the copying party myself, some saints are still Liu Hong, don't say it's Zu Chongzhi).

Liu Hong (about 129 210 A.D.), the character Yuan Zhuo, a native of Mengyin County, Taishan County, Eastern Han Dynasty (now Mengyin County, Linyi City, Shandong Province), a descendant of Liu Xing, King Lu of the Eastern Han Dynasty, an outstanding astronomer and mathematician in ancient China, the inventor of the abacus, was respected as the "Saint of Calculation" by later generations.

He was intelligent and studious since childhood, well-read in the six arts, and was knowledgeable, especially in astronomy and calendar; When he was young, he stepped into the official career and was recruited to the capital Luoyang by the Taishi Order, and was awarded Langzhong, and later moved to Changshan Changshi.

He wrote the book "Dry Elephant Calendar", which is the first calendar in China to introduce the theory of uneven lunar motion. The length of the return year of the eclipse is set as the sun, and for the first time, the intersection angle of the white and ecliptic is given at about 6°1 of ancient degrees. The length of the perigee month measured is days, which is very different from the current measured days.

Later, he annotated the "Nine Chapters of Arithmetic" and wrote the "Nine Chapters of Arithmetic Notes"; He successfully invented the "positive and negative number abacus", so he was called the early founder of the "abacus" and the father of the abacus. Linyi people will be counted as the saint Liu Hong, with the wisdom of the saint Zhuge Liang, the book saint Wang Xizhi, and called the "Langya three saints". Please adopt.

There is a temple of five sages in Wang Xizhi's former residence.

Do you have different household registrations? Or is the child moving to Linyi? If the husband and wife belong to different households, and one of them first enters the household, pays the social maintenance fee, and then transfers it to the other party, the supplementary payment is required.

This is mainly to prevent some couples from taking advantage of the different payment standards in different regions.

The inventor of the "abacus" and the discoverer of the theory of the unevenness of the moon's motion were revered by later generations"Count it holy"。

He is known as a mathematician and a writer in Tianjin.
