Gunpowder, paper, printing, and the compass are sometimes called the Four Great Inventions of Ancient China. Kites were first used as a way for the army to signal warnings. Umbrellas were invented for protection from the sun as well as the rain. Chinese doctors knew about certain herbs to help sick people.
a few big ones were:
compass - ppl can travel long distance w/o getting lost. both on ground n water. very important 4 trade.
paper - allow ppl to write on. much more convenient than marking on stones. it led 2 passing n spreading of knowledge.
silk - very light but strong fabric made from silk worm. nice material dat got traded far away n hence the silk road.
gun powder - china invented black powder be4 everyone else. only prob was instead of using it in wars, they made fireworks 4 show.
