The image shows the entrance of a building with a large purple banner that reads "50 years old" in Chinese characters. The building appears to be a modern, two-story structure with a flat roof and large windows. The entrance is made of concrete and has a set of stairs leading up to it. There are several potted plants and flowers on either side of the entrance, adding a touch of greenery to the space. The sky is overcast and the ground is wet, suggesting that it has recently rained.
