When was the peak of the development of ancient science and technology in China?

There is no doubt that it was the Song Dynasty. Three of the four great inventions were completed in the Song Dynasty and spread all over the world. The culture of the Chinese nation has experienced thousands of years of development and reached its peak in the Zhao and Song Dynasties-Chen Yinque's "gunpowder, compass and printing"-these are the three great inventions that indicate the arrival of bourgeois society. Fire [crab medicine] blew the chivalry to pieces, the compass opened the world market and established colonies, while printing became a tool of religion, in general, a means of scientific rejuvenation and the most powerful driving force for creating the necessary premise of spiritual development. " -Karl Marx

We should pay attention to the strength, efficacy and results of these inventions. People will see that these inventions are far less remarkable than the three great inventions; These three great inventions were unknown to the ancients, and their origins are still vague and unknown. They are: printing, gunpowder and magnets. Because these three great inventions have changed the face and state of many things in the whole world, first of all, literature, second of all, war, and third of all, navigation, and thus have produced countless changes, so that it seems that no empire, any faction, or any planet can have greater power and influence on human affairs than these technological inventions. British philosopher bacon

1, compass (the technology of making compass [crab] was first put forward by Shen Kuo (Gong Yuan1031-1095) in Mengqian Bitan). With a compass, ocean navigation is possible. Movable type printing (Bi Sheng invented movable type printing, he was the first inventor in the world, and he printed movable type books about 400 years earlier than German J Gutenberg. This is a necessary prerequisite for the development of civilization. ) 3. Artillery (The history of human war entered the era of hot weapons, and the gun body was cast with iron, and spherical explosive shells cast with pig iron were fired. 1 126, Jin people besieged Bianjing. When Li Gang was guarding the city, he bombarded the retreating nomads with lightning. "At night, there was thunder and lightning, and the crowd was excited.")

4. Deep-well drilling technology (Zhuotong well is a salt well that sucks brine with upright and thick bamboo tubes. Zhuotong well was invented in the Northern Song Dynasty and the Qing Dynasty (Yuan 104 1 ~ 1048), more than 800 years earlier than in the West. Its caliber is only the size of a bamboo tube, but it can drill wells as deep as tens of feet. Known as "the fifth greatest invention in ancient China" and "the father of oil drilling in the world". The scientific and technological circles have an image metaphor for Zhuo Tongjing: "Without Zhuo Tongjing, there would be no Gulf War". 5. Paper money (Jiaozi is the earliest paper money used in the world, which was issued in Chengdu in the Northern Song Dynasty (1023). The paper money used in Europe was issued by the Swedish bank in 166 1 year, but it was only a stopgap measure at that time, not as a real currency. 6. Watertight bulkhead (warship of Song Dynasty (960 ~ 1279)) has generally adopted watertight bulkhead technology, which improves the unsinkability. It can protect the ship from sinking due to water, and it is still an important structural form in ship design. The discovery of Nanhai No.1 proves that China was the first country to invent this technology. ) 7. Canal lock in the form of compound sluice (In 984, Huainan transshipment made Joe take charge of the Huaihe River, while Erdoumen was a canal lock in the form of compound sluice, thus improving the transportation capacity of the river. After affecting the world. ) 8. Abacus (Zhang Zerui drew an abacus in The Riverside Scene at Qingming Festival. It can be seen that as early as the Northern Song Dynasty, abacus was widely used in China. The official appearance and popularization of abacus calculation was in the Song Dynasty and Yuan Dynasty. ) 9, musket (originated in China, improved, inherited in the ALB world, carried forward in Europe. The earliest known musket in the world is a bamboo musket with a barrel of 10 in the Song Dynasty, which was recorded in the Fire Dragon Classic written by Jiao Yu in the Ming Dynasty. Iron drums and the earliest pistols (hand spears and pistols) appeared in Jiyuan dynasty in 13. ) 10, taiji diagram (the ancient taiji diagram was painted on pottery in Xia and Shang dynasties more than 3000 years ago or earlier. There is an S-shaped curve in the circle, and the black and white yin and yang points are added later. Today's Tai Chi map is generally considered to be made by Zhou Dunyi in the Northern Song Dynasty. ) 1 1 trademark (It is said that there was a Liu's steel needle shop in Jinan during the Northern Song Dynasty. The steel needles produced by this shop are of high quality and low price, which is quite famous in the local area. In order to make the business continue to prosper, the shopkeeper made a "white rabbit" copper plate with pictures and words on it. The copper plate is square, with a picture of a white rabbit in the middle. The books on both sides of the painting have the slogan of the name of the store "Jinan Liujia Needle" and "Recognize the white rabbit in front of the door as a memory". This "White Rabbit" copper coin was destined to be a darling as soon as it was born, because it was the earliest special trademark in the history of China. Song people have famous brands in all walks of life. For example, there are famous "Pan" in the ink industry, and "Shujia Umbrella" with Lin 'an 84 bone and purple bamboo handle in the umbrella industry, all of which were first-class brands at that time. ) 12 advertising (in the commercial operation of the song dynasty, advertisements printed with copper plates also appeared, which was more than 300 years earlier than in the west. As far as bachelor Su Dongpo is concerned, he once wrote an advertisement poem for an old woman who cooked oil, which made it prosperous. ) 13 football (kick is kick, bow is ball). Cuju is kicking the ball with your feet. It is considered as the embryonic form of football. In early 2004, FIFA publicly confirmed that football originated in China. ) 14 fireworks (mainly used for military and grand ceremonies or performances, while the modern global activities that can set off fireworks on the same day are generally New Year's Eve activities. ) 15 Chess (The Song Dynasty began to finalize the design, and in addition to the invention of fire [crab medicine], "cannon" and "scholar" and "elephant" were added. At present, the earliest chess score that China can see is recorded in the Book of Shilin Guang Ji in the Song Dynasty, which is more than 200 years earlier than the western chess score. ) 16 nunchakus (founded by Zhao Kuangyin, Song Taizu, formerly known as big panlong stick (also called big broom in modern north) and small panlong stick (small broom). However, at that time, the big panlong sticks were short and long, which were specially used to sweep away the clues of the enemy, break the armour or hard weapons, and make them lose their fighting capacity. Later, this weapon spread from the south to the Philippines and from the east to Japan. Due to historical changes, nunchakus were changed to their present appearance) 17 lifebuoy (Han Zhongwu sent the imperial power to Jinshan in the Song Dynasty and ordered him not to cross the river by boat. So the kingship gave each soldier a "floating ring" to let them cross the river, and finally completed this task. At that time, the "floating ring" used by royalty was the predecessor of modern lifebuoy. ) 18 Landmines (1277 Landmines were used in the war between the Song people and the Mongols. Song Jun used the "fire [crab] gun" buried underground (that is, armored mine), which was further developed in the Yuan Dynasty. ) 19 Grenade (China first invented, Yuan 1000 A kind of firearm called "fireball" or "cannon" appeared in Song Dynasty, and its principle is the same as that of modern grenades. In 1044, the art of fireball from thunderbolt, fireball from tribulus and fireball has been included. /kloc-in the 0/3rd century, the iron shell explosive weapon "Thunder in the Sky" has appeared in China's army, which is almost the same as modern grenades. ) 20 poison gas bomb (poison smoke bomb, because the main function of this kind of smoke bomb is to smoke out the enemy with poison gas. In addition to sulfur, flame nitrate and charcoal powder, various toxic substances such as croton, wolfsbane and arsenic are also infiltrated into the formula to see its effect. ) 2 1 flame thrower (Song people used double pistons to continuously spray flame on the oil pump. There must always be a flamethrower in Wu Jingli.) 22 Blow up the [river crab] bomb (yuan 1000) A man named invented the fire tribulus, and added arsenic, asphalt, tribulus terrestris and so on. Go to the recipe of black fire [river crab] and make the original fried [river crab] bomb. ) 23 Rockets (In the third year of Kaibao (970), Feng Jisheng, the minister of the Ministry of War, proposed the rocket method. Five years later, rockets were used in the war with Nantang. ) 24 A three-bow bed crossbow (also known as the "eight-ox crossbow") needs 100 people to twist the shaft and pull the string. The arrow "wooden iron ridge" is commonly known as "one gun and three swords", which is roughly like a javelin and three iron ridges are like three swords. The crossbow can also shoot "step arrows" and nail them to the wall in rows. The siege soldiers climbed up by climbing. Wei Pi once improved the bed crossbow, which greatly increased the range. Wei Pi Biography: "The old bed crossbow stopped shooting 700 steps, which increased Pi by a thousand steps." In the Song Dynasty, one step was1.536m, and a thousand steps were1.536m, which was one of the highest halberd records reached by ancient long-range weapons. Overprint color printing (Overprint color printing is the earliest color printing in the world, and it is a complex high-precision printing technology developed on the basis of block printing. According to historical records, in the Northern Song Dynasty (960- 1 127), copper plate printing with three colors of cyan, blue and red appeared.

26 time-telling robot (the most amazing thing is that there is a time-telling robot (the god of cymbals), which will automatically knock the cymbals 8 times every quarter of an hour. Although copper cracks have been invented and applied in China for thousands of years, their shapes and sizes are different, and their timing methods and principles are the same. ) 27 crystal lens (Shi Ling, a fellow countryman and friend of Su Xun, used a crystal magnifying glass when law enforcement officers handled the file. ) 28 silver salt blackening development technology (the discovery of the principle of color fixing was first seen in Su Shi's "Compassion for Things": "On the halogen window paper, the baking is obvious." Spinning (a simple lathe equipped on spinning, specializing in metal cutting and machining). In the early years of the Northern Song Dynasty, the use of machine tools became more common, which was a milestone in the history of machining. ) 30 chain drive (China invented chain drive-chain drive belt in 976; Europeans didn't start using chain-driven belts until 1770, about 800 years later than China. )

3 1 Coking (During the Southern Song Dynasty, China invented coking to smelt metal with coke, which greatly improved the purity of smelting metal. Europeans didn't know about coking and using coke in metallurgy until the early age of 18, which was more than 400 years later than China. ) 32. The method of frying copper with bile soil (this method only exists in the lead mountain field of Xinzhou. According to the abridgement of Volume 33 of Song Shu Shi huo Ji, the ancient pit in Qianshanchang ... where there is no water, it is bravery soil. Dare to fry copper, less work, endless soil. "This is to take bile soil first, and then introduce water to drench the soil, so as to obtain bile water. Because the concentration of extracted bile water is very low, it must be boiled and concentrated before it can be used for copper leaching. ) 33 Cam (China invented the cam in 983-983, and applied it to the heavy chain lifted by water power. At the same time, cam was used in a sizing workshop in Tuscany, Italy. The 34-axis warping method is more effective than the rake warping method in the Tang Dynasty, which leads to the transition of fabric structure from plain weave to twill and from warp to weft. ) 35-rod piston bellows (according to Dr. Needham's research, written in 1280, titled "Fighting Birds") This kind of bellows is light, labor-saving and efficient, and has been popularized and developed quickly. The piston bellows does useful work in both forward and backward strokes, and in each stroke, one end exhausts air and the other end sucks in the same amount of air at the same time, so it can provide continuous airflow and improve the blowing efficiency, which is a great progress in blowing technology. There are 36 spinning wheels (the structure consists of twisting, winding, transmission and prime mover. The prime mover is a big round wheel similar to the rope wheel of a manual spinning wheel, and the axle is equipped with a crank, which needs to be shaken by two hands of a special person). Water spinning wheel (water-powered water spinning wheel appeared in the late Southern Song Dynasty. The Yuan Dynasty prevailed in the Central Plains and was mainly used for processing linen and silk. It was an advanced textile machinery in the world at that time. It can spin 100 kg in one day and night, about 400 years earlier than western hydraulic textile machinery. China people have started to use belt-driven looms in Hebei (1 1). The Silkworm Book written by Qin Guan records the structure, several key components and usage of the silk reeling car in detail. The power is generated by the pedal, and the silk thread is wound on the spool. This book is the earliest record of cars. ) 39 blast furnace ironmaking (the predecessor of modern steelmaking furnace, decarbonization is realized by repeated forging with blowing cold air. )

Chapter 9 of Mathematics (Qin wrote Chapter 9 of Mathematics, put forward the method of "seeking a skill by seeking a great derivative", and established the solution of "simultaneous congruence formula", which was 500 years earlier than the related research of European mathematicians Euler and Gauss) 4 1 gap product method (gap product method is a method to solve the accumulation problem and the high-order arithmetic progression summation problem. ) 42 cholesky decomposition's root graph (a triangular numerical table, which is actually a coefficient table of binomial theorem of positive integer indicators, is about 400 years earlier than the similar results of Al Cassie in the west, and is called Jiaxian Triangle in the history of mathematics (also called Yang Hui Triangle, because it appears in Yang Hui's book). According to the root graph of the root method, Jia Xian created the open method of multiplication and multiplication, and provided a method to solve the approximate value of the positive real root of any higher order equation. ) 43 Method of multiplication and division (Jia Xian's method of multiplication and division was put forward 800 years earlier than that of Italian Rooney and British Horner) 44 Nine-fold method (various calculation methods of abacus multiplication and division) 45-day celestial technique (Ye Li's "Measuring the Circle of the Sea Mirror" and "An Ancient Yan Duan") systematically discussed the "celestial technique" (that is, the one-dimensional higher-order equation) for the first time. ) 46 stacking technique (Yang Hui put forward "stacking technique" on the basis of Shen Kuo's "notch technique", which promoted the research of higher-order arithmetic progression. ) 47 Composition law of higher-order vertical and horizontal graphs in combinatorial mathematics (Yang Hui) 48 Formula of calculation algorithm (which is helpful for the application and popularization of agile algorithm. ) 49 Lotus Leak (in the eighth year of Tiansheng (1030), the lotus leak invented by Yan Su used the overflow system for the first time, which improved the timing accuracy of the leaky kettle unprecedentedly. ) 50 image of aquatic instruments (Su Song successfully developed the image of aquatic instruments in Yuan You for seven years (1092), and realized the idea of the trinity and coordinated operation of armillary sphere, armillary sphere and time telling. It can not only observe and demonstrate the astronomical phenomena, but also time and tell the time. It already has the scientific structure principle of modern observatory's opening, telescope rotating clock and mechanical clock. It is the earliest astronomical clock in the world. ) 5 1 A new method of imagery (Su Song has made outstanding contributions to star map drawing. His famous astronomical work "A New Imaging Method" is accompanied by five star maps, which is the first time to adopt a more scientific all-star representation. ) 52 Lingtai Secret Garden (during the reign of Emperor Yangdi (1049- 1054), astronomer Zhou Yan presided over the re-survey of 28 constellations and Sunday stars. The result of this experiment is to sort out 345 constellations, and this catalog is included in the secret garden of gv 10, and the number of stars received exceeds. ) 53 Star map (Yuanfeng period (1078- 1085) has a high accuracy of star measurement, and its star map is preserved in the form of stone carvings, which is the existing astronomical map of stone carvings in Suzhou Museum. The upper part and the lower part of the star map are inscriptions, which is a precious cultural relic for studying the whole sky in Song Dynasty. ) 54 calendar (when Yang Zhongfu presided over Ning Zong, the length of the tropical year measured in the calendar was 365.2425 days, which was completely consistent with the current Gregorian calendar, but nearly 400 years earlier than the western Gregorian calendar. (Shen Kuo rebuilt the calendar and put forward a more scientific new calendar, that is, replacing the lunar calendar with the twelve calendars, which was more than 900 years earlier than the similar twelve calendars formulated by the British astronomer Schonaber. 56 Mercator projection (is an isometric cylindrical map projection method. In 940, China invented Mercator projection; 1568, Britain used Mercator projection, which was about 600 years later than China. Jiaxian Triangle (also called Yang Hui Triangle and Pascal Triangle) is a geometric arrangement of binomial coefficients in the triangle. ) 58 Chronology of Twenty-four Solar Terms (This new calendar, in which the twenty-four solar terms are uniformly adjusted in the positive four order, is extremely beneficial to agricultural cultivation. ) 59 magnetic declination (Shen Kuo discovered the existence of magnetic declination by accurately measuring meridian circle, 400 years earlier than Europe. ) 60 biological solid foundation technology (using the unique ecological characteristics of marine life, many bridges across rivers and seas have been built. Liang Shi Bridge across the sea at the mouth of Luoyang River in Quanzhou, Fujian, is 5m wide and 1000m long. This magnificent bridge has a history of 950 years, and people still walk on it today. ) 6 1 boat (the largest is 36 feet long (about 1 10 meter), equipped with 24 wheels and 6 "shoulder poles", carrying more than 1000 foot soldiers. ) 62 Armored Ship (1203), Master Qin built a "flat sea bream with iron wall and shovel mouth" warship with a load of 1000 (about 60 tons). The bulkhead is equipped with iron plates, which is the first armored ship. The bow is equipped with a sharp iron head shaped like a shovel mouth, which is used to impact the plow in a water war. Low center of gravity fluid damping device (the ship has a small hole with a cover at the bottom of each cabin, which is called "water hole" by ship technical experts. When sailing, the rain or spray splashed on the ship can flow into a connected mezzanine cabin at the bottom of the ship through the "water hole", and the water in the mezzanine cabin reduces the center of gravity of the ship and makes the ship run more smoothly. Due to the inertia and internal friction of the water in the cabin, the fluctuation of the ship caused by wind and waves will be partially offset. Hongqiao (Flying Bridge) is a columnless wooden beam arch bridge (i.e. barrier beam arch), which has reached the highest level of ancient wooden bridge structure in China. Dock (refers to the artificial construction on the shore, as a place to build and repair ships, but also as a berth for ships. Dock can be divided into dry dock, irrigation dock and floating dock. Dock was invented by Zhang Ping of Song Dynasty in China. ) 66 rattan boat (Shenzhen-Guangzhou coastal state army, thinly nailed tung oil, shipbuilding tied with empty boards and vines. In the cracks of vines, madder from the sea is dried and suffocated, and rises when it meets water, so that the ship does not leak. Its ship is so big that businessmen use it when crossing the sea. ) 67 Chinese sailing boat (floating in the South China Sea, the boat is like a huge room. If the sail is hung in the sky, the boat is dozens of feet long, and hundreds of people in a boat accumulate food for one year, among which tapirs make wine, and they are born and die. ... and the big food country crossed the west sea to Mulan Yong country further, and its ships increased. A ship can hold thousands of people, and the ship is organic, otherwise it will take several years to arrive, unless it is a huge ship, it is impossible to arrive. "The largest China ship has 12 masts, while the small boat has three masts. ) 68 Modular System (Wood-based modular system and number of quota system are adopted in wood-based buildings, which makes the architectural design and construction standardized to a certain extent. ) 69 Kimchi (1 178 "Answer outside the Ridge" has recorded the technology of storing water in a clay pot in a sealed way, which is the first time to store food in a kimchi pot. ) 70 air mill (a mill that uses wind to rotate. ) 7 1 sand filtration technology in dark shed (10,000 hectares of fertile land were added) 72 Sugar frost spectrum (Wang Zhuo wrote the world's first monograph on pond building) 73 Treadmill (a kind of human plow, which reduced the dependence on livestock. )

Plough mirror (equipped with plow mirror, it is convenient to turn over the soil, thus increasing agricultural output. The emergence of new tools has also greatly increased crop yield. ) 76 Double cropping system of rice and wheat a year (the so-called "double cropping of rice and wheat a year" means planting wheat after rice harvest, and planting rice in the same field after wheat harvest. Its realization has improved the land utilization rate and increased farmers' income, which is a great progress in technology and economy. 77 Jiatian (1 149 Jiatian building is recorded in Chen Fang's agricultural book, and it is the earliest artificial cultivated land in China. The measures of deep ploughing, freezing and fumigating the soil to warm the field are adopted to make use of the cold-soaked field. ) 78 fertilizer accumulation technology (1 127- 1279 minerals such as lime, sulfur and milk powder have been used as fertilizers. Before 1 149, fertilizer accumulation technologies such as compost, fire fertilizer and cake fertilizer fermentation appeared. Establish a manure bank to maintain the effectiveness of fertilizer. (1 149 years ago, deep ploughing, sun exposure, freezing and heavy soil were adopted in rice field cultivation in southern China to promote soil maturation. The technology of cultivating strong seedlings appeared. And know how to master the law of climate change, sow in time to prevent rotten seedlings. ) 80 distant grafting technology of fruit trees (1067 successful record of distant grafting of fruit trees. Ginkgo biloba and olive were harvested by "bamboo hoop tree" and "salt-wrapped tree", eggplant seedlings were embedded with sulfur, and trace elements were used for vegetable cultivation. ) 8 1 Mulberry grafting technology (Mulberry grafting technology was invented in Zhejiang and Zhejiang in the middle and late Northern Song Dynasty, which was a revolution in the history of mulberry cultivation and greatly promoted the development of sericulture in Zhejiang and Zhejiang) 82 "Tang Hua" technology (1232- 1298). ) 83 poultry artificial incubation technology (1 174 poultry artificial incubation technology appeared. Quails are kept as caged birds. ) 84 Veterinary Hospital (1007) The establishment of sick horses is the beginning of the establishment of veterinary hospitals in China. )

Domesticating goldfish (12 14 years) goldfish changed from wild to artificial domestication. 1243, live fish were transported by mechanical devices. The long-distance transportation technology of fry is well documented. ) There are 86 prescriptions of Taiping Sheng Hui (including Chinese medicine prescriptions 16834, more than Ganjin prescriptions in Tang Dynasty 10000). Vaccinate against human pox (the eldest son of Wang Dan, the prime minister of the Northern Song Dynasty, died of smallpox. Prime Minister Wang didn't want others to catch this disease again, so he invited famous doctors and magicians from all over the country to find some ways to treat and prevent it. A Taoist priest in Emei Mountain presented a prescription: "inoculate" healthy people with an attenuated human pox vaccine through nasal mucosa, so that people can gain immunity to smallpox. ) 88 medical departments (medical departments are also divided into 9 departments: 1. Internal medicine ii. Rheumatism (such as stroke) 3. Pediatrics 4. Ophthalmology 5. Otolaryngology 6. Skin and orthopedics 7. Obstetrics 8. Acupuncture 9. Trauma and curse) 89 anatomical drawings (Yang Jie, a famous doctor and poet, summed up the anatomical experience of condemned prisoners and described it as. ) 90 Three Causes-Prescription and Medicine Theory of Disease Syndrome (the complicated causes are divided into three categories: internal cause, external cause and internal and external cause). Although this classification is similar to that described by Zhang Zhongjing in Han Dynasty, its content has developed, that is, it summarizes various causes more specifically, and its scope is more comprehensive, which is more in line with clinical application. The principle of three-factor classification has always been followed by later doctors. ) 9 1 acupuncture atlas (Wang has made great contributions to acupuncture. He studied predecessors' works, combined with his own experience, determined the location of acupuncture points in detail and compiled an acupuncture map. In the fifth year of Tiansheng (1027), he was ordered to cast two bronze statues of acupuncture, which was very convenient for acupuncture teaching, clinic and examination. He also made his own works. 92 prescriptions of pediatric medicine (this book is called "the originator of pediatrics", which has a great influence on the formation and development of pediatric medicine. ) 93 The Complete Collection of Women's Prescriptions (written in the first year of Jiaxi (1237)) is the most systematic and comprehensive gynecological monograph in the history of traditional Chinese medicine, which is divided into three parts of gynecology and five parts of obstetrics. 94 The Total Record of Holy Traces (an encyclopedia in the history of medicine) is a collection of a large number of diagnoses, prescriptions and prescriptions in the previous generation and the Song Dynasty. In the seventh year of Chunyou (1247), the Collection of Injustice was written, which was the first systematic monograph on forensic medicine in the world. Song Ci should be regarded as the father of forensic medicine. Before modern [crab] archaeology was introduced to China, ancient bronzes and stone carvings were the main research objects. Inscriptions, similar to those in Europe, are considered as the precursors of archaeology in China. The research object belongs to sporadic unearthed cultural relics or handed down products, which have not been scientifically excavated; Attach importance to the description and textual research of inscriptions, and the purpose of research is to supplement history with classics. Formed in the Northern Song Dynasty, it was officially named "epigraphy" in the Qing Dynasty. ) 98 Taizu Changquan (Song Taizu Changquan, known as "Song Taizu 32-potential Changquan" in ancient times, also known as "Taizu Boxing", is one of the six famous boxing in China Wushu circle. ) 99 Fan Trace Boxing (formerly known as Yanqing Boxing). The Huo family who moved from Cangxian County to Jinghai County, Hebei Province, called this kind of boxing Fan Trace, which was passed down from generation to generation, and later became very famous, and Fan Trace was also famous for it. ) 100 express (a fast military mail system serving military purposes at high speed-urgent delivery) came into being at this time. This kind of quick foot delivery includes walking delivery, horse delivery and quick foot delivery. Fast feet are the fastest, 400 miles a day. There are different distances between shops, 10 miles and 20 miles. It is reported that the water-based instrument camera designed by Shanghai Cui Shi Science and Technology Co., Ltd. has successfully won the bid for the "Design, Manufacture and Related Service Procurement Project of Water-based Instrument Camera Exhibition in China New Science and Technology Museum". At present, the largest 1:2 water camera in China will be stationed in the new Science and Technology Museum in June this year. At that time, people will be able to appreciate this large-scale ancient astronomical instrument composed of armillary sphere, elephant and timekeeper, and feel the extraordinary wisdom of ancient China ancestors.
