“You can either travel or read, but either your body or soul must be on the way.” ── Roman Holiday

During the postgraduate period, on the basis of finishing all the courses and dissertations on time, I took nearly every opportunity to travel in Europe. Traveling seems to be an exploration and communication of the outside world, however, actually, it is a process of carefully listening to your own monologue in the inner world. Who am I and what would I live after getting rid of the stress of fast-paced urban life? Finding another self, purifying the worldly soul, even if the feeling is too fleeting, this is also worthy to remember and appreciate forever.
