What achievements of ancient Chinese culture in truth are living Chinese people proud of?

During the period of geographical discoveries, Europeans dreamed of opening Asia for sales markets. They believed that undeveloped aborigines lived in this territory. But it turned out that in the Middle Ages, China and India already had their own developed products that were in no way inferior to European ones. Today’s Chinese people have the right to be proud that their state was one of the first to start producing high-quality paper. Further, typography was born. They already knew writing and were actively trading in the domestic markets. Gunpowder was also used in China.
