Why were singers called "actors" and teachers and storytellers called "gentlemen" in ancient times? Isn't teaching and telling stories dirty?

Who told you that the teacher is an inferior and respected teacher? The founder of teaching is Confucius, the most sacred teacher. Do you think the founder of Confucianism is a scumbag? Ancient times was a class society. Scholars are the first of the four people, scholars are scholars, and those who learn well are officials. In other words, reading is to prepare for being an official, but there is no official car. Where are you going? First, medicine, not a name, is a famous doctor; Medicine has become a continuation of scholars, but teaching. People who seek advice are officials, and Confucianism is respected as Confucianism. A memorial tablet will be set up in the gentry's home, saying that "heaven and earth are teachers", which is based on it. In the Republic, there is no king, but heaven and earth are close teachers, that is to say, teachers are second only to their parents. Do you think they will be inferior? Storytellers are called gentlemen because they are just honorifics. In ancient times, artists were untouchables, and they did not give up their humble membership. For generations, they were basically illiterate. Although the rhetoric in Quyi is also very particular, it is all written by literati. Artists can only recite stories, but not read books. Therefore, among artists, storytellers have a slightly higher level of education, and ordinary people address them as Mr., but this gentleman.
