Nostalgia syndrome

With the rapid development of China's first-tier cities, problems such as housing, work, hukou, and education have become unbearable for young people living in large cities in other provinces and cities. Once the sense of superiority, belonging, and security faded away, the urban aura eclipsed, stress, high intensity, and anxiety rose up together, undercurrents of "nostalgia syndrome" surging. "Nostalgic syndrome" in such first-tier cities is not just a 'symptom', it is also an emotion.
