On March 24, the prison held a chess (dark chess) competition for the cultural and recreational activities of the detainees in March. A total of 36 detainees (including the mentally and physically elderly detainees) played against each other. During the game, sometimes tense and sometimes relaxed, the inmates racked their brains to think hard in order to win on the chessboard. In the end, the inmate of Aishe, who is skilled in chess, won the championship.
