Generally speaking, I feel oppidans' living presure is extremely heavy. And their unrealistic comparison minds are stronger than countrymen's. Living in city, people pay more attention to better jobs and name brand effect of dressing. If he/she is a white-collar, he/she will look over himself/herself more advanced than others. Regardless of more or less earning, he/she feels satisfaction and superiority. Just because of the aura of white-collar, they have to pay more than others. And also have to save their so-called faces in front of others. They must chase better dressing and be busier in their living styles. Only when void nights, will they feel inner fear and emptiness. They are lonely and doleful. They never enjoy simple and unadorned feeling among common people. There stand thick walls between peoples' minds. They can't discern each other. Urban people always wrap themselves up carefully. Although they are neighbours or colleagues and can meet everyday, they actually know seldome each other.
