After the steps of Lingyun Road, on the hillside towards the subway station, I just saw the sun setting in the west. At this time, it was almost dusk. I also completed this trip to Lushan. It took about four hours to cross the size of the two mountains, excluding the time to go down the mountain. It takes physical strength, hone the will, and stand on a high place to see the scenery. This is probably the meaning of climbing.
