In ancient times, people wrote on bamboo strips or silk. Bamboo was heavy and difficult to Carry. Silk was too expensive for ordinary people. Then kyo on invented paper using tree bark and old cloth. This new material was light, cheap and easy to use. Paper allowed ideas to be recorded and shared more easily than before. The second invention is printing. Before printing, books were copied by hand, which took many years. b. Shang invented movable type printing using clay blocks. This made IT possible to print many books quickly. Knowledge could spread far and wide. More people could learn to read and understand the world around them. The third invention is the compass. When sailors traveled across the sea, they often lost their way. Compass, which always points north, became their guide. With this simple but powerful tool, explores, could sail safely to distant lands, IT connected different cultures and opened up new worlds. The fourth invention is gun powder. Chinese chemists discovered how to make gun powder by xing. Certain materials. At first, I was used to create beautiful fireworks that look up the night sky. Later, he played an important role in protecting the country and shaping world history. These foreign tions show the wisdom and creativity of ancient chinese people. They did not only change china, they change the whole world. today. We still benefit from their great ideas. We should remember their contributions and feel proud of our heritage. Thank you.
