caption: The image shows a subway station with people walking on the platform. On the left side of the image, there is a train on the railway track with glass doors. At the top of the platform, there are sign boards and lights. In the middle of the picture, two people are walking, one of them holding a bag in their hand and the other holding an object in their other hand. There is a poster on the wall with some text and images on it, and a dustbin on the floor. The poster reads "Stay Safe" and is part of the MTR's new campaign.
