Detailed explanation

"There is no distinction between high and low jobs, only the social division of labor is different." Even in today's enlightened society, it is still impossible to evaluate every job rationally, soberly and objectively. Its roots generally come from the class division and business classification that began in Shang Dynasty and lasted for thousands of years.

In this era of "laughing at poverty rather than prostitution", people's values and moral concepts have undergone fundamental changes. The new era, new society and new world have actually derived a new division of "upper, middle and lower reaches", which is the inevitable development of today's society and the sorrow of social development.
