The image shows the entrance of a tunnel with a white door on the right side. The door has a red and white sign with Chinese characters on it, which appears to be warning people not to enter the tunnel. On the left side of the door, there is a blue wall with a mural of a wave-like design. The floor is made of concrete and there are several potted plants and flowers on the wall. The tunnel has a metal railing at the top and a small window on the left wall.
