In the old alley in 1980, Shen Qingwu was learning to develop photos under the green tile eaves of his photo studio. Gu Jingchen from the watch shop next door always came to borrow darkroom light bulbs. The clock he built can tell the time, and the photos she took can "speak". The marks of the two times meet under the eaves. Later, when he went south to do business, she took care of the photo studio and turned it into an old photo album restoration shop. Thirty years later, the white-haired Gu Jingchen returned with the stopped clock. Shen Qingwu dug out the black-and-white photo taken of him from the dusty iron box - the young man in the photo was leaning against the green tile wall, his smile brighter than the sunlight at the corner of the eaves. Old things are not old, they are just waiting for the wind to meet again.
