He remembered a TV series where someone was locked in a very small house, no windows, and the door only opened through a tiny hole when food was delivered. Every person stayed in that little house all year round, in a room less than eight square meters, with a single bed and a chamber pot. This was the life of the prisoners. Liu Rui and the others were first taken to the warden's office, where they presented the materials about Liu Rui's father that had been prepared in advance.
Liu Rui looked carefully; there were some photographs, some were serious ID photos, and others were candid shots of his father and others working.
In fact, if the warden hadn't told him that these were his father's materials, he really wouldn't have been able to recognize the person in the photographs as his father. There wasn't even a single resemblance to the father he remembered.
