High Line Park (The High Line) was planned after the retirement of the original railway line, and the main body is actually similar to a viaduct. Walking in it is like walking in a garden hanging in the air. On both sides of the road are a variety of buildings, there are office buildings, apartments, and old buildings that have been a bit old for a long time, and you can see artistic graffiti from time to time. This time we came for a walk, it happened to be late autumn, and we often saw trees in autumn, which was very pleasant.
