Chinese civilization is not only a treasure of the Chinese nation, but also a lot of magical gifts to the world. These contributions are worthy of the pride of every Chinese and should be remembered by every Chinese child.
"The Great Four Inventions" is a children's picture book with the theme of the Four Inventions and using vivid and interesting stories as the main line. This book introduces the brilliant inventions in Chinese civilization in a more acceptable way - papermaking, printing, compass and gunpowder.

"Awesome Papermaking: A Story Moving Journey", the story background of this book is a father-son trip. The simple adventure tells the whole story of papermaking. From the earliest text oracle bone inscriptions, the ancients have begun to work hard to record the stories happening around them with symbols and words, but before there is no paper, there are many challenges in the recording and inheritance of these texts. Until papermaking was invented through continuous attempts, the story of our great nation could continue.
At the end of the book, a small parent-child interaction experiment is also included. Children can try to make paper with their parents. The knowledge in the book becomes paper they make themselves, which can give children a deeper experience and a huge sense of accomplishment.
"The Great Compass: The Great Challenge of the Valley", before the invented compass in ancient times, people could only choose the sun in the sky and conspicuous stars as tools for distinguishing directions. This way of identification is very simple but also has great flaws. In order to get rid of the limitations of nature, the ancients began to pay attention to observation and finally invented the compass that could lead the times.

"Great Printing: Magic of Paper and Ink in Calligraphy and Painting", printing is another great invention after papermaking. If paper can record history, then printing is to better spread history. It is not enough to have paper to make the ancients' thoughts span thousands of years, because it is time-consuming to copy repeatedly by human hands, and it is difficult to get the effect of dissemination. The invention of printing technology has quickly expanded the brilliant achievements of civilization. The explanation of printing is also very vivid, using things that children can come into contact with as metaphors, which is close to their original cognition.
"Great Gunpowder: Xiao Hei Job Search Record", I think the invention of gunpowder is an opportunity to rise in China, but unfortunately we missed it again and again. This book tells the story of a gunpowder named Xiao Hei who has gone through many dynasties and has also taken on different jobs, from exploring immortality to urban magic, to surprise soldiers in the army, and finally becoming an assistant to the great dreamer of mankind. Nowadays, Xiao Hei has become more gorgeous and more popular among people. Xiao Hei is gradually playing a greater role in his jobs and finding his true value.

civilization continuation is the accumulation of national wisdom, and the inheritance from generation to generation has led to the prosperity of today. The four great inventions are the wealth left by our ancestors. When we stand on the shoulders of giants, we will definitely go further away, and let these great inventions shine in the hearts of every Chinese.
