I was hiking the Jinshanling section of the Great Wall at 4am for a sun rise view. There were few other people before or behind me in the distance recognizable by their moving flash lights, but many a time I was completely alone in the darkness, feeling my way up along the unrestored wall. My senses were wide open, grabbed by the feeling of undisturbed freedom coupled with a rising tripidation as if something was hiding in my invisible surroundings.
It turned out that the humidity was too strong in the air and the sun could only vaguely shine through the clouds. It was soothing though to have the morning breeze gently drying the sweat from hiking while hearing the cheerful noise from the birds and insects and following the extension of the Wall into the far away mist.
