According to historical records, Emperor China had thirteen brothers, nicknamed Tianling. One of them invented numbers, and then invented heavenly stems and earthly branches. Invention numbers: zero, one, two, three, four, five, six, seven, eight, nine, ten, twenty, thirty, thirty, one hundred, one thousand and ten thousand.
In addition, the ancients often used heavenly stems to represent the number 1- 10, such as: A, B, C, D, E, F, G, Xin, Ren and Gui. In ancient China, there was another memory method called "preparation", which was more convenient to write, and was widely used when Arabic numerals were not popularized and used in China.

Generation of digital symbols:
The earliest tools used by human beings to count are fingers and toes, but they can only represent numbers within 20. When the number was large, primitive people mostly counted pebbles and beans. Gradually, people were not satisfied with counting by grains, so they invented the method of knotting to describe counting, and described counting on hides, bones, trees and stones.
In ancient China, counting was done with sticks made of wood, bamboo or bones, which was called counting chip. These counting methods and symbols gradually became the earliest digital symbols (numbers).
Today, all countries in the world use Arabic numerals as standard numbers. Arabic numerals were introduced into China around 13 ~ 14 century. At the beginning of the 20th century, with the absorption and introduction of foreign mathematical achievements, Arabic numerals began to be used slowly in China, and have become the most commonly used numerals in people's study, life and communication.
