Hang Jin added: "Liu Jipin admitted that Li Yanyan's jumping from the building 20 years ago was related to him, and you knew that he planned to kill people. He also said that you have been threatening him with his murder all these years, and he gave you a lot of money. He gave you all the money, and his wife divorced him because he had no money to take home."

Zhuang Shiqiang: "Yes, I know that he killed someone. He planned Li Yanyan's jumping off the building 20 years ago. I accidentally found out about it, so he threatened me. It will make me regret it for the rest of my life. And he has been threatening me with this matter and using me all these years."

"You hold the evidence of his murder in your hand, and you can let him threaten you. If you say this, who do you think will believe it?" Both of them speak in an orderly manner, and Hang Jin really can't intuitively determine who is lying.
