Special Stamp Issue - "Four Great Inventions of Ancient China"

How would the world look like if there is no compass, paper, printing and gunpowder? Ancient Chinese had an advanced understanding of the sciences of physics, engineering, chemistry and astronomy. Their numerous discoveries and inventions have shaped the development of science and impacted on human civilisations around the world. These ancient inventions have profoundly changed the world since they emerged many centuries ago. The compass ushered in a brave new world of exploration and trade; the invention of gunpowder changed warfare tactics through the development of weaponry; and printing and papermaking facilitated the spreading of knowledge to lay the cornerstone for modern education.
