Brief introduction of Fung Lung College

During the Five Dynasties, the academy began to appear as a new educational place. According to "The History of the Unified Qing Dynasty", lee woon-jae Fenglongshan, a famous figure in the Northern Song Dynasty, founded Xi Zhong Academy and Fenglong Academy, and took students to give lectures, which initiated the education of Hebei Academy. In the Northern Song Dynasty, there were three recorded Hebei academies, all of which were in Fenglongshan. One is Fenglong Academy, at the foot of Yangshan Mountain in Fenglong Mountain. It was originally a place where Gong Li gave lectures in the Han Dynasty, and was founded by Liu Yun in the Five Dynasties. Original lecture hall, reading hole, etc. There are two clear springs in the courtyard, one is Mengquan, which is clear and sweet and is the source of water diversion for the academy. Mo Chi, also known as the pen washing pool, is said to be the place where the ancients washed pens. Another academy is west of Longshoufeng, named Xixi Academy, "the place where the hermit Yao fled in the Tang Dynasty". There are nine classics in Song Dynasty, with Zhang Zhu as the head of the mountain. He used to be a masterpiece of Hebei, which was gradually abandoned by later generations. His address is about Beilongchi Village. Xi Zhong Academy is under Longshou Peak, and reading literature is called Zhongfeng Academy. According to records, this is also the place where Liu Yun teaches. In the Northern Song Dynasty, "Zhang Gongfu Tea, the head of the mountain, gathered hundreds of people one after another". It was the largest academy in Hebei at that time. Later generations abolished it, and its address was under the concept of truth. The Fenglong Academy in Yuan Dynasty developed unprecedentedly and entered its heyday. In the first year of Emperor Xianzong of Mongolia (A.D. 125 1), Ye Li (1kloc-0/92-1279), a famous mathematician in Luancheng, Hebei Province, ended his exile and returned from Jindong, where he "set up a field to seal Longshan, benefiting many disciples". He devoted himself to research and tirelessly taught others. With the support of villagers, Marshal Shi, calm inspector and famous scholar Yuan Haowen, he rebuilt the lecture hall and revived the Hong Long Academy. Here, Ye Li further summed up and studied China's ancient celestial skills, developed and innovated them, supplemented and revised his "Circle Measuring Sea Mirror" written in Shaanxi, collected the achievements of China's celestial skills, popularized them, and wrote a book "An Ancient Yan Duan" in an easy-to-understand language, which is inexhaustible. Ye Li has made a series of research achievements in the fields of stone points, medicine, astronomy, temperament and Taoism. It can be said that peaches and plums are full of gardens and have achieved remarkable results. Ye Li founded celestial algebra and got the equation six times. It is not only a great development of primitive semisymbolic algebra in ancient China, but also at least 300 years earlier than European algebra, and it has a frontier position in the history of mathematics in the world at that time. His two gobbledygook books established his important position in the history of world mathematics in the13rd century and the history of natural science in China. Today, Bailudong Academy, Maoshan Academy, Shigu Academy and Donglin Academy, which have played an important role in the promotion of feudal Confucianism in China and Neo-Confucianism in Zhu Cheng, are all listed as cultural attractions in China. Hong Long Academy, which has a prominent position in the history of science in China, is not famous as a classic. This is a pity and misunderstanding. After Ye Li, Gaocheng Ren An Xi presided over Hong Long College. "Its teaching to honour, technology first. Disciples come and go, often as many as 100 people. " "The Quartet has come and achieved a lot." The old site of this university is being restored. Redding Cave remains the same. There is a cave with oil lamps and books in it. There is a small door between the two caves, and there is a thick trace of black smoke in the cave. At the mouth of the cave stands the monument "Never chisel a rock" published by the magistrate of Yuanshi County in the light years, and there is an icon room of the Ming Dynasty 20 meters in front of the cave.
