In the fall of 2008, I had just finished half a semester of my first year of junior high school and stopped going to school. I lied to my family that I was going to find a good friend to work together in a county not far from home. In fact, it was not the case. At that time, when I was 15 years old, I boarded the train from the county seat to Beijing alone, going to the Beijing that I had visited countless times in my dreams. From then on, my voyage and wandering began. At that time, the innocent boy had only seen the beauty and beauty of the city on TV. The neon lights flashing every night in the city, and the endless traffic. Everything was so attractive, but he had no idea that that beauty was so out of reach in the real world.
