Black powder, compass, printing. The dawn of human civilization-the earliest long-range weapon of fire-the earliest bow and arrow tool-the greatest contribution of stone tools to the world is the practical disease prevention and treatment technology. China is an ancient country of mathematics, and Nine Chapters of Arithmetic and Nine Chapters of Numerology are ancient mathematical masterpieces. China is also an ancient country in astronomy, and China is the first country in the world to record astronomical phenomena such as sunspots, Halley's comet and supernovae in writing. In addition to papermaking, compass, gunpowder, movable type printing and four new inventions of traditional Chinese medicine, 10 decimal system, equatorial coordinate system and block printing, there are many ancient inventions in China that affect the development of world science and technology, such as porcelain, silk, metal smelting and casting, and intensive farming. Twenty-four solar terms are regarded as the fifth greatest invention in ancient China, and many new advances have been made in physics, chemistry and biology. Our ancestors created two golden ages for the prosperity and development of ancient science and technology in China. China is a traditional agricultural country, and water conservancy is the lifeblood of agriculture. In ancient times, there were Dujiangyan, Zheng Guoqu, Lingqu, Longshou Canal and the Beijing-Hangzhou Grand Canal before the Tang Dynasty. The Beijing-Hangzhou Grand Canal built in Sui Dynasty is the earliest and longest navigable canal in the world. These projects are incomparable to medieval Europe in terms of building scale, technical level, and the benefits of agricultural irrigation, navigation and transportation. Mozi was a representative figure of Mohism in the Spring and Autumn Period and the Warring States Period. In his book Mo Jing, he put forward geometric concepts such as point, line, square and circle. The Operation Method of Pythagorean Theorem in Zhouyi ·suan Jing. Nine Chapters of Arithmetic, written in Han Dynasty, contains solutions to 246 applied problems, which is very rich in content. It has made great achievements in arithmetic and algebra, especially in solving practical problems, far exceeding the mathematical system of ancient Greece. Zu Chongzhi's pi calculated by secant technique is very accurate and far ahead in the world. What needs special mention is the outstanding contribution of ancient China to the development of world civilization-"Four Great Inventions", which embodies the wisdom and creation of working people in ancient China. The compass was invented in the Warring States period more than two thousand years ago. At that time, people ground natural magnets into spoon shapes and put them on a smooth plane, pointing out the north-south direction. This navigation instrument is called "Sina". In the Northern Song Dynasty, the compass was made by artificial magnetization. Ceng Gongliang recorded the making method of "compass fish" in the book "General Classics of Martial Arts" edited by 1044. Shen Kuo, a great scientist, further explained the method of making compass with magnetized iron needle in Mengxi. The compass was used for navigation shortly after its invention, guiding China's ocean-going fleet to sail in the South Pacific and Indian Ocean, and was introduced to Arabia in the12nd century, and then to Europe. The invention of papermaking was summed up by the working people in China from the experience of bleaching and retting hemp, which began in the Western Han Dynasty. Ancient paper of the Western Han Dynasty unearthed from the beacon tower site of Luobuzhuoer Khan in Xinjiang is all plant fiber paper, and its texture is rougher than others. Cai Lun, who was in charge of the Royal Handicraft Workshop in the Eastern Han Dynasty, relied on sufficient manpower and material resources, improved the papermaking technology with rags, bark and old hemp as raw materials, and produced a batch of practical paper with higher quality. Paper-making technology first spread to Korea and Vietnam, Japan in the seventh century, Arabia in the eighth century and Europe in the thirteenth century. The invention of printing went through two stages, from block printing to movable type printing. About the Sui Dynasty, people invented block printing technology under the inspiration of seal cutting rubbing method. During the Northern Song Dynasty (about A.D. 104 1- 1049), Bi Sheng, a civilian inventor, invented the movable type printing technology, which made movable type from clay and then typesetting and printing. It was economical and convenient, greatly improved the efficiency, and was a great revolution in the history of printing. In the Yuan Dynasty, Wang Zhen successfully invented wooden movable type and wheeled typesetting frame. The invention of gunpowder began with alchemy. In the process of alchemy, the alchemist accidentally found that igniting the mixture with nitrate, sulfur and charcoal as the main raw materials would cause combustion and explosion. After the invention of gunpowder, it was used in military affairs, which changed the face of war and the course of history. As Marx said, "gunpowder blew the knight class to pieces." In the War of Resistance Against Gold in the Northern Song Dynasty, Song Jun used powerful gunpowder weapons such as "thunderbolt" and deafening sound. By the end of the Song Dynasty, gunpowder sand guns and gunpowder guns were invented. Gunpowder was introduced to India and Arabia by merchants from 1225 to 1248, and later to the west. China's science and technology have been in the leading position in the world for a long historical period. The purpose of revealing and exploring the scientific creations and inventions of our ancestors is to better inspire young people's studious and pioneering hearts. Today, history has entered the era of sound, light and electricity, and the dissemination of knowledge and information is vivid and intuitive. This book adopts the form of "illustrated pictures and texts", showing historical features and various images, and narrating historical facts with "words". Illustrated with pictures and texts, it shows readers the fruitful achievements of the development of civilization in the motherland for thousands of years. Although this book is called Illustration of Ancient Inventions in China, some items in it are not inventions in a strict sense, such as some astronomical phenomena, which were first observed by our ancestors and belong to the content of discovery. But because it plays an important role in social production practice and people's daily life, it is of great significance and groundbreaking, and we will also talk about it in this book. For another example, some academic works have made a true and complete record and description of inventions in a certain field. The achievements of scientific research in history are mainly summarized and circulated through works, such as Zhou Jing and Wang Zhennong's Book. We also received this book. For academic works with similar contents in the same subject, we only choose those written earlier to introduce and tell. This book does not adopt the framework of chronicles, and is basically arranged in the order of astronomy, calendar, physics, chemistry and chemical engineering, geoscience, biology, agriculture, medicine, light industry, metallurgical machinery, architecture, navigation and aviation, military affairs, culture and art, but there is no strict classification. Some items are different in content, such as gunpowder, one of the four great inventions, which is introduced in Invention of Gunpowder and Gunpowder Weapons. Another example is planting mulberry and raising silkworms, which is described in "Sangji Fish Pond" and further elaborated in the relevant items of "Textile". The purpose of doing this is not only to take care of the convenience of narration, but also to let readers master relevant knowledge more comprehensively and accurately. Moreover, the contents of the items are different, but at the same time they are focused. China's traditional culture is profound and colorful, and there are many documents and classics handed down. In the past, similar publications only introduced inventions and discoveries in scientific and technological fields. In fact, our ancestors also had unique inventions in the field of social sciences, such as Chinese characters, poems and songs, melodies, ancient musical instruments and so on. They are all important components of the development of human civilization and have played an important historical role in promoting social development. To this end, we have added some related items in social science, which is the uniqueness of this book. In the selection of drawings, in addition to displaying artifacts, we also pay attention to the modality of ancient scientists when they wrote and invented and the social life scenes at that time, showing readers the strange and interesting touching stories of indomitable scientific masters in the process of invention and creation, enhancing the sense of history and artistic appeal, and making readers further understand the hardships of inventors.

Hope to adopt
