The earliest appearance of rope can be traced back to tens of thousands of years ago. When humans began to have the simplest tools, they would twist grass or tiny branches into ropes. People use it to bind wild animals and huts.
Make a belt and tie it on the grass skirt. Then, a "knotting note" appeared, which recorded the event with a knot the size of a rope. This is how people remember things before the birth of words.
Basic introduction
Indians living in Peru used to take notes by tying knots widely. They use a thick rope as the main rope, tie different colors of auxiliary ropes to represent different things, and tie different knots on the rope to represent different numbers, so as to achieve the purpose of recording. At present, there are still some people in the world who have no words to use this primitive method.
Knot is a rich legacy left by our ancestors, and there are many ways to do it. There are hundreds, but there are actually more than one hundred. Before nylon rope appeared, people used cotton, hemp and straw rope.
It is mainly made by hand twisting, and there are still many tying tools among the people. Now nylon rope and plastic rope are very common, and their endurance and quality have been greatly improved, so they are easy to carry.
