How were the classes in ancient China divided?

before the Han dynasty, it was divided into: doctors-scholars-common people

after that: scholars, peasants, workers and businessmen

"common people" without official positions were commonly called "common people" in ancient times. Scholars are between "doctors" and "common people", some of them are officials who live in food cities with salaries, and some of them are people who earn their own living. The so-called "learning to be excellent is a scholar". Therefore, in ancient times, there were titles of "scholar-bureaucrat" and "scholar", but later "scholar" generally referred to "scholar".

in China's ancient traditional agricultural society, the "people" were divided into four people: intellectuals, peasants, workers and businessmen. "History of Hanshu Food Goods" says: "Scholars, farmers, workers and businessmen have businesses; Learn to be a scholar. "
