Zhongzhou science and technology is also very developed, just taking the Eastern Han Dynasty as an example. During the Eastern Han Dynasty and the Emperor, eunuch Cai Lun summed up the previous experience in Luoyang, Kyoto, and invented papermaking, which contributed to the spread and development of China culture and world culture. Another example is Zhang Heng and Zhang Zhongjing in the Eastern Han Dynasty, who were famous astronomers and medical scientists in Chinese history.

(1) The great astronomer Zhang Heng and his hometown Nanyang. Zhang Heng, Ping Zi, was born in Xi 'e, Nanyang County, Eastern Han Dynasty (now Nanyang County, Henan Province). Zhang Heng was born in a noble family in Nanyang. Grandfather Zhang Kan was a prefect of Shu County. Zhang Heng has shown intelligent talent since he was a teenager. When he was young, he went to Luoyang, the capital of the capital, and entered the Imperial College. Although he was superior to the world, he was calm and calm.

Zhang Heng likes astronomy, calendars, arithmetic and so on. When Emperor An of the Eastern Han Dynasty heard that Zhang Heng was good at arithmetic, he sent a bus to take Zhang Heng to the capital, where he was appointed as a doctor and promoted to Taishiling. During this period, Zhang Heng seriously studied the calendar and astronomical phenomena, created the world's earliest armillary sphere that was rotated by water power, and wrote mathematical works such as "The Theory of Calculation Outline" and "Calculate it through the network". In the first year of Yangjia (132), Zhang Heng created the Houfeng seismograph, which was the first instrument in the world to determine the orientation of earthquakes. The seismograph is made of fine copper, with a diameter of eight feet. It is covered and raised, and looks like a wine statue. The surface of the instrument is cast in the shape of seal characters, mountains, turtles, birds and beasts. There are eight dragons on the watch, with their faucets in all directions. The dragon mouth holds a copper pill, and there is a toad under it, ready to take it. All kinds of organs are respected, and the organs are connected to Longkou. If there is an earthquake in any place, the dragon facing the earthquake will spit out the copper pill and fall into the toad's mouth, and the vibration will be louder and louder, reporting the direction of the earthquake to people. Although Yi Long started the engine, the other seven dragons would not move. On one occasion, scholars in the capital blamed the dragon hair machine, which faced west, for not moving. A few days later, the postman came to report that there was an earthquake in Longxi, and "everyone was amazed at its wonders." Since then, historians have watched the seismograph record earthquakes.

Zhang Heng also drew China's first relatively complete star map, and made a south-pointing car, an automatic memory drum car and so on, which made great contributions to the development of science and technology in China and the world. Zhang Heng is also a writer and painter, and his works, Erjing Fu, Sixuan Fu and Nandu Fu, all have high literary value. In memory of Zhang Heng, the World Science Organization once named craters on the moon and planets in the universe after him.

Xia Village, Nanyang County, Henan Province is Zhang Heng's hometown, with "Ping Zi's Old Reading Site" and Zhang Heng Memorial Hall. Zhang Heng's Tomb is in Little Shi Qiaocun, Nanyang County. The tomb is eight meters high and 79 meters in circumference, surrounded by an octagonal flower wall. The great scientist Zhang Heng is buried here.

(2) Zhang Zhongjing, a medical sage, and his hometown of Nanyang. Zhang Zhongjing was born in Nanyang County (now Nanyang City, Henan Province) in the Eastern Han Dynasty. Since he was a teenager, he has been unusually intelligent, diligent in learning and good at thinking. He has learned from Zhang Bozu, a famous doctor in the same county. When Emperor Ling of the Eastern Han Dynasty, Zhang Zhongjing once "raised filial piety and was the prefect of Changsha", but at the end of the Eastern Han Dynasty, eunuchs were authoritarian, the court was in a daze, the officialdom was dark, and the people were in poverty. With the prevalence of typhoid fever among the people, many people died, so he abandoned his official position and retired to study medicine. Zhang Zhongjing extensively collected prescriptions, summed up the experience of the previous generation, and practiced medicine among the people. He wrote sixteen volumes of Treatise on Febrile Diseases (two versions of Treatise on Febrile Diseases and Synopsis of the Golden Chamber, which were adapted by Wang Shuhe, a famous doctor in Jin Dynasty), and summarized the eight categories of yin, yang, exterior, interior, deficiency, excess, cold and heat in TCM diagnosis, and the treatment methods such as sweating, vomiting, purgation, warming, Tao and harmony.

The methods of diagnosis and treatment summarized by Zhang Zhongjing have become the criterion for future generations of Chinese medicine practitioners to practice medicine and make great contributions to the development of Chinese medicine. Zhang Zhongjing was called "medical sage" by later Chinese medicine.

shortly after Zhang Zhongjing's death, a "medical shrine" was established in his hometown to commemorate this medical scientist who made great contributions to human health and Chinese medicine. The "medical shrine" is a quaint cemetery on the bank of Wenliang River in the eastern suburb of Nanyang City, which is divided into two parts. After entering the gate, there is a tower-shaped pavilion on both sides, which is 13 meters high and decorated with rosefinch paintings. There is a stone screen door on the inside of the gate, with a brief biography of Zhang Zhongjing engraved on the front and a preface to Treatise on Febrile Diseases engraved on the back. The gallery in the courtyard is inlaid with a group of paintings of Zhang Zhongjing's life with stone carvings, as well as 117 stone portraits of ancient Chinese famous doctors.

Behind the stele gallery is the "Tomb of Zhang Zhongjing, the medical sage of Changsha Prefecture". Fiona Fang, the tomb of Zhongjing, is 33 meters long. There is a tomb pavilion with cornices and flowing corners on it, and there are temples, main halls and east-west temples behind it. There is a statue of Zhang Zhongjing in the main hall. The original woodcut edition of Treatise on Febrile Diseases and more than 1, volumes about Zhang Zhongjing's medical history are collected in the temple, which was collected by Zhang Shaozu, the forty-sixth generation grandson of Zhang Zhongjing during the Tongzhi period of the Qing Dynasty.

Zhang Zhongjing was a great TCM doctor in the Eastern Han Dynasty. He first treated diseases with various kinds of Chinese medicines, and was called the originator of cube. His Treatise on Febrile Diseases was regarded as a medical canon by later generations. Zhang Zhongjing became the founder of Chinese traditional medicine and was called "the sage of medicine". At present, there is "Zhang Zhongjing Medical University" in Nanyang City, Henan Province. In 1982, Chinese and foreign medical professionals held a seminar on Zhang Zhongjing's medical thoughts here to study and commemorate this great TCM doctor.
