In Prague, July 10, 1973, eight people were killed when a stall truck was opened on the sidewalk in Prague. Li Jia told the police that she did it on purpose! After that, the local newspaper received a confession sent by Luo Jia before the incident, which was not only her indifference and coolness, but also revealed a broken soul rejected by the rest of the world: she had food and clothing in her middle-class family, had no loving relationship, and her mental state and loneliness made her run up against a brick wall in her work and life, and she, who longed for love, was unable to fill the huge void in her heart. She looked profoundly at the world she didn't love, and letters for help never arrived, so she stepped on the gas door. Her collision and report have also pushed her and others onto the road where there is no way to return.
