In early July 2019, I flew from Hong Kong to the United States, eager to explore the unheard-of and experience the unseen. I struggled to adapt to countless new experiences, clumsily learning to cook, interacting with people of different races and skin colors, and participating in a variety of activities. Every day was full of novelty for me. The months in the United States felt like a dream, surreal yet so real, as if traveling through a parallel universe in Doraemon's time machine, experiencing a different life. Just when you've grown accustomed to everything and immersed yourself in it, time silently traverses three time zones. These were days worth remembering, days etched deeply into my heart, days that I'll vividly recall even many years later.
