Why is this small city 'perfect' ? a Colombian guitarist knows

Colombian guitarist Qiao Bai (Barrada) shared a heartwarming story about a band performance: during a show in an ancient town, although the band played foreign songs, the elderly audience listened with remarkable focus. Their simple yet sincere attention deeply moved him. To him, Yiwu may be small, but it is full of surprises—friendly people, rapid development, and a strong sense of safety. This vibrant city has long held a special place in his heart as a truly "perfect city."
