2. A seemingly simple suicide case hides a huge secret. In order to uncover this secret, a group of people spent seven years, paid countless prices and even risked their lives. Jiang Yang, a prosecutor who had a bright future and was safe and sound, was imprisoned for three years for accepting bribes and corruption, and once again appeared in public view as his body curled up in a suitcase, which was transported by a famous local lawyer, Juck Zhang. The case attracted the attention of the whole city, and Interpol Yan Liang stepped in to take charge of the case and confronted Juck Zhang head-on. Juck Zhang admitted his crime, but when he was sentenced by the court, he retracted his confession on the spot and provided an alibi. The case has reached a dead end.
