Inventions of the Tang Dynasty

The Tang dynasty created and invented many things during their time of reign.One invention of the Tang that highly contributed to their society is Gunpowder.Gunpowder was invented in China during the Tang dynasty,and was an important invention in their time period because they lead to many new uses such as being used to treat skin diseases and as a spray to kill insects,that was,before it was later used in guns,fireworks and rocketry. Gunpowder was made from the mixture of charcoal,sulfur and saltpeter(that's what the website said).
Gunpowder was invented by Emperor Wu Di and a group of alchemists,who spent a bunch of time doing research trying to create external life(which is  what all other emperors tried to do).It was first used to treat skin diseases and also as a spray to kill insects and bugs.Prior to the invention,people began experimenting with the gunpowder,they later made bows with tubes attached to them(filled with gunpowder),they fired arrows with it,they then found out they could just fire the tubes themselves because of all of the power from the pressure of the escaping gasses.
Gunpowder has really changed people's lives in many ways.For example,it is now being used by all of the armies all around the world(well,most of them).It is really being used inside guns to propel(force)the bullets out of the gun to fire the gun.
