China's urbanization process has progressed to the current stage, and it has changed from the helpless choices of the previous generation who were difficult and indifferent to a natural idea. "Working" can no longer enter the post-90s language family and work in a favorite city. It is as natural as "finding a company job for college students". Regardless of their hukou and housing, these people are already real urban people. They can no longer go back to the village or small county where they were born. In the rapidly changing China, It is the evolution of these concepts that are truly profound. What does this text mean? ['Post-90s urbanization is an unconscious process.', 'Hukou and housing are no longer necessary for urbanization.', 'The evolution of ideas is a sign of the new stage of urbanization.', 'The term "part-time job" will gradually withdraw from the stage of history as urbanization progresses.']
