The video shows a crowded underground walkway in a subway station. People are walking in both directions. The walls and ceiling are decorated with arched patterns. A person wearing a green jacket is pulling a cart loaded with a bulky, covered item. Another person in a black hoodie walks alongside the cart. A child is sitting on the cart, partly visible among the covered items. Many other people are walking by, some carrying bags or backpacks. The floor is tiled with dark stone. A directional sign hangs from the ceiling.
