Former residence of luoxiahong

Former residence of luoxiahong

Luoxiahong's former residence is also known as xingxingyuan, luoxiahong Memorial Hall and the home of the old people during the Chinese Spring Festival Located in the core reserve of Langzhong ancient city, Sichuan Province, which is a national famous historical and cultural city, an excellent tourist city in China, and the hometown of Chinese Spring Festival culture, it is a beaded two-way residential courtyard rebuilt in memory of luoxiahong, an outstanding ancient astronomer and calendar in the world and an old man of Chinese Spring Festival.

Location overview

Luoxiahong's former residence faces south, covering an area of about 400 square meters. There are 21 houses with wooden structure, carved doors and windows, and blue tile roof. On January 29, 2006 (the first day of the first month of the Spring Festival in the third year of the lunar calendar), it was officially opened to the public for visitors to visit.

Walking through the courtyard and into the main hall, the first thing you see is the sitting figure of Luo xiahong. The statue was created by Professor Wu mingwan, a famous sculptor from Langzhong. There is a plaque hanging above the statue, on which is a collection of characters by Mi Fu, a great calligrapher of the Song Dynasty, "Bingyao Qianqiu", praising Luo xiahong's achievements.

Profile

Luoxiahong, a man of Langzhong in Bajun County in the Western Han Dynasty, is a city of Langzhong today. When he was young, Luo xiahong was in the countryside and devoted to observing the celestial phenomena. Later, he became famous in his hometown. He was recommended by his fellow countrymen, Taichang Ling Qiao long and Taishi Ling Sima Qian, and was recruited to Beijing by Emperor Wu of the Han Dynasty. Together with the official astronomers Tang Du and Deng Ping at that time, he developed the calendar. This calendar was adopted by Emperor Wu of Han Dynasty and issued in the first year of Taichu, so it is called Taichu calendar. This is the first complete written calendar in the history of our country, which has an extremely important position in history. Luo xiahong's pioneering contributions to astronomy, mathematics and agriculture have been recognized by the academic circles. Joseph Needham, a British historian of science and technology, called him "the most brilliant constellation in the history of Chinese astronomy."

On September 16, 2004, with the approval of the small object Nomination Committee of the National Astronomical Union, the National Astronomical Observatory of the Chinese Academy of Sciences named the asteroid with international permanent number 16757 "luoxiahong star". Since then, luoxiahong has truly become a bright constellation, forever shining in the starry sky.

Character contribution

There are 12 exhibition rooms in luoxiahong's former residence, focusing on his life story, main achievements and great spirit. Joseph Needham, a British historian of science and technology, made a comparison between the eastern and Western astronomical achievements of Luo xiahong's time in his book the history of science and technology in China, and listed them as ten major achievements, among which there are three.

Compilation of Taichu calendar

First, he compiled the Taichu calendar. First of all, let's get to know taichuli. At that time, because the calendar developed by Luo xiahong and Deng Ping was "the most dense of all the strings, the sun and the moon are like a wall, and the five stars are like beads", which was much better than the other 17 calendars, it was adopted by Emperor Wu of the Han Dynasty and promulgated in the first year of the Taichu period, which was called the "Taichu calendar". In order to recognize Luo xiahong's achievements, Emperor Wu of the Han Dynasty gave him the post of servant, but Luo xiahong refused, and Deng Ping was appointed as taishicheng.

It can be seen that the Taichu calendar has made great progress compared with the six ancient calendars. There are nearly 100 kinds of calendars in Chinese history, and the main ones are listed in the chart. It can be said that they are all the results of improvement based on the "Taichu calendar" created by Luo xiahong.

Put forward the theory of huntian

The second achievement is the "huntian theory".

Luo xiahong created the armillary sphere (including the armillary sphere and the celestial phenomena), which vividly displayed the model of the universe. Through long-term observation and scientific calculation, he proved the theory of huntian theory and the law of celestial body movement with facts, and finally worked out the "Taichu calendar" which was superior to the other 17 calendars, which was a powerful negation of the theory of Gaitian by huntian theory.

It is proved that Luo xiahong created the armillary sphere in the treatise of Yang Xiong, a great writer and astronomer in the Han Dynasty, historical records and the old book of Tang Dynasty.

Common rate of invention

The third big achievement is the success rate. In mathematics, he invented the method of "continuous fraction (division by turns) to find progressive fraction", which was named "tongqiri", which is called "luoxiahong algorithm" by modern scholars. "Luoxiahong algorithm" is 600 years earlier than aiyahata, an Indian mathematician who used similar methods, and 1600 years earlier than Pemberley, an Italian mathematician who proposed the continued fraction theory. It influenced Chinese astronomy in 2000.

Establish the first month as the beginning of the year

It is another great achievement of Luo xiahong to establish the calendar day system with the first month of Meng Chun as the beginning of the year.

In ancient times, Zhuanxu calendar took October as the first month of a year, which was not conducive to farming, but also not suitable for the four seasons. Luo xiahong changed the old calendar system in the early days of Taichu period. He stipulated that the first day of the first month of mengchun should be the first day of the year, which was adopted by Emperor Wu of Han Dynasty.

After Luo xiahong established the first month as the beginning of the year, people called the first day of the first month as "New Year's Day" and "New Year's Day", and the folk used to call it "New Year's Day", and the folk also had the saying of "Spring Festival", which is still in use today. Therefore, today, we also respectfully call Luo xiahong "the Spring Festival old man".

24 solar terms in calendar

Luo xiahong incorporated 24 solar terms into the calendar for the first time. This practice laid the foundation for the Spring Festival and was also a pioneering work that will benefit thousands of generations.

Character influence

After the promulgation of taichuli, Emperor Wu of the Han Dynasty appointed xiahong as a servant (consultant). He left but did not accept it. He went back to Langzhong to continue to study astronomy and passed on his profound knowledge to future generations. Under his great influence, Langzhong in the Han and Tang Dynasties became a famous astronomical research center in ancient China, with talents and brilliant stars.

At the end of the Western Han Dynasty, the famous astronomers Ren Wensun and Ren Wengong appeared in Langzhong. Zhou Shu, Zhou Qun, Zhou Ju and three generations of astronomers in the Three Kingdoms period. Today, the street where Zhou's grandparents and grandchildren live is named "Guanxing Street". Yuan Tiangang and Li Chunfeng, the astronomers and feng shui masters of the Tang Dynasty, settled in Langzhong to study astronomy and mathematics. As early as the Tang Dynasty, there were memorial buildings of tiangongyuan and Chunfeng temple, as well as the tombs of Yuan Tiangang and Li Chunfeng, which are now becoming the pilgrimage and experience places of Fengshui culture tourism in Langzhong.

From the commemorative meeting of UNESCO, to the asteroid named after him by the International Astronomical organization, as well as the records of various dictionaries, ancient books and local chronicles, and the publicity of various newspapers, magazines and film and television works, people cherish the memory of Luo xiahong, the world's outstanding scientist, in various ways. Langzhong people cherish the honor he has brought to their hometown. They not only commemorate him by building the star watching tower, naming "Changgong Avenue" in Qili New District, rebuilding "constellation garden", setting up the website of "Spring Festival old man" and Issuing the luoxiahong commemorative medallion, but also regard him as an example of learning forever. We use these ways to make this great man shine in our hearts forever.
