Night clan is a positive image. At the same time, many people in today's society belong to night owls. Among the night performers, there are urban white-collar workers who are constantly striving to realize their personal values, social elites who are constantly happy for family life, entrepreneurs who are constantly striving for their careers, experts and professors who are constantly dedicated to the prosperity of the country and the nation, and so on. They have spread all over the society. They are doctors, teachers, lawyers, entrepreneurs and so on.
