What are the methods and detailed steps of making a fire in primitive society?

There are three ways to make a fire in primitive society: drilling wood, saltpeter and lightning.

The method of drilling wood for fire is: take a piece of bamboo, drill a small hole, and fill it with a certain amount of dry straw and other combustible materials. Then, take a straight stick with a diameter larger than the bamboo hole and sharpen one end of it as long as the tip can be stuck in the bamboo hole. Finally, after fixing the bamboo in a certain position, insert the tip part of the stick into the small hole and rub it hard in the palms of both hands with the stick. When the bamboo hole is heated, the flammable materials next to it will catch fire. At this time, the hand not only does not stop, but also blows air into the flammable materials caught in the bamboo holes until the flammable materials are completely burned. At this time, drilling wood for fire is completed.
