I always discuss with my friends what is popular right now, such as fashion, popular TV series, and popular novels. Recently, I discovered that all of them have one thing in common, which is "travel". Nowadays, "traveling" is becoming more and more popular, especially clearing. Unfortunately, my roommate and I are one of them, always dreaming of one day traveling through time, just like the heroines in all novels, being able to watch the flowers blooming and falling in front of the court with the people they love, and watching the clouds roll and relax in the sky. In ancient times, we not only lived an ordinary life, but also lived our own wonderful life.
