Seven days after the old man passed away, the empty convenience store had a row of out-of-place wooden shelves. The medicine bottles on the shelves are mottled and old, and the price tags silently indicate the currency systems of different eras; Lao Shi's children secretly threw away the "garbage mountain", only to reappear the next day; I stared at the increasing number of old things on the shelves, and only the blood pressure and pills were left with a faint blue fluorescence - only the dying can buy medicine in this store.
