woman sitting on a very long staircase, giving a thumbs up. The staircase is made of gray stone and has railings on either side. In the distance, there is a large opening in a mountain. There are people climbing the staircase in the distance. The video then cuts to a view of the staircase leading up to the mountain opening, shrouded in fog. There is a sign in Chinese and English that says "Steps are dangerous walk slowly." There are many red tags hanging on a barrier near the sign. People are walking up and down the staircase.
