As one of the four great inventions, how was gunpowder first invented?

China was the first country to invent gunpowder. The earliest appearance of gunpowder was closely related to the alchemist family from the Warring States to the early Han Dynasty. The emperors and nobles were intoxicated with the gods, hoping to live forever. During the refining process, they gradually popularized some alchemists and Taoists' elixirs and invented the gunpowder formula. In the Sui Dynasty, gunpowder was mainly developed by synthesizing saltpeter, sulfur and charcoal.

The most famous alchemists are Ge Hong and Sun Simiao. Everyone knows that Sun Simiao is a great physician in China. He made great contributions to medicine and was later called the king of medicine by the world. In fact, Sun Simiao is also a famous alchemist, calling himself "Sun Zhenren".

He collected many secret recipes of alchemy families in Heluo area and Guanzhong area by using the alchemy formula summarized before, and finally put forward the sulfur fire method-a more useful formula. In a word, the invention and spread of gunpowder can not be separated from Sun Simiao.

When gunpowder was first used, it was not used in the military, but in the acrobatic troupe of the Song Dynasty, or in puppet shows.

Although many people have a good understanding of the characteristics of sulfur and charcoal, not everyone can combine saltpeter, sulfur and charcoal in a certain proportion to make gunpowder. If an alchemist hadn't accidentally invented gunpowder, there wouldn't be gunpowder in China.
