Ancient information transmission story: In ancient greece, a philosopher named socrates was considered one of the greatest philosophers. One day, a student gave him a watch as a gift. He told the students that the watch was a tool he used to measure time, but he didn't want to keep it with him because it might reveal his intelligence. He suggested that the student give the watch to his friend so that he could better use the gift to spread his wisdom. In ancient China, a philosopher named Confucius also paid great attention to information transmission. He once said," A gentleman is not a tool." It meant that a gentleman should not be just a person but a tool with the ability to spread knowledge and education. He once founded a school to spread his wisdom and knowledge through teaching courses, and also to spread his ideas through writing.
