Traveling through more than 50 neighbourhoods on a small train, we arrived at Chitta in the southern suburbs. Although I did not see the library of Hogwarts College of Witchcraft and Magic, I was surprised to find a free museum and a delicate little bookstore. Looking at the recommendation notes posted on the shelves by the reviewers, I bought a bigger Brownie sundae to take a nap on the lawn at Chicago's popular dessert store. Despite the embarrassment of cursing your vagrants all the way without lunch, there are also fears that you will stop to show your way and kindly help you return the staff who should not have refunded your ticket. In short, chaos and warmth are always entangled with each other. The ups and downs make you feel the truth and beauty of the city.
