Many young couples talk about marriage after their relationship has developed to a certain stage, and meeting their parents is the first step to form a family. Seeing parents is also valued by many people, especially the feelings and impressions of each other when they get along for the first time, which is likely to affect the later development. A young man in Liaoning met his girlfriend's parents and was killed by his girlfriend's father because of a contradiction, but it was hidden for three years before it was discovered.

Zhang Yu is a young man in Fuxin, Liaoning. 20 16 retired and returned to his hometown. Zhang Yu, then eighteen, met a high school girl who opened a restaurant at home, and the two later developed into lovers. At the beginning of 20 17, the father of this high school girl wanted to meet Zhang Yu, so on 20 17 15, Zhang Yu went to his girlfriend's house. In the process of going out with Zhang Yu, Zhang Yu's girlfriend's father Cai had a dispute. Then Cai used tools to kill Zhang Yu and burn the body.

For Changyu's murder, Cai used another way to cover up the truth. He lied that he was injured by Zhang Yu, and then Zhang Yu escaped. Ms. Liu, Zhang Yu's mother, still believes what Cai said at that time. After that, Cai visited Ms. Liu for three consecutive days to inquire about the whereabouts of Zhang Yu, and bluntly said that Ms. Liu had hidden him. Cai's behavior is to cover up the truth, and the other is to observe the movements of Ms. Liu's family.

Later, because Zhang Yu couldn't be contacted, Ms. Liu began to doubt slowly, but Cai's wife always sent a text message to Ms. Liu in the tone of Zhang Yu to appease her, and at the same time mailed a gift to Ms. Liu in the name of Zhang Yu on holidays. Three years later, Ms. Liu realized that she might have been cheated and called the police. In March 2020, Mr. and Mrs. Cai were arrested and confessed their crimes. This incident is very surprising. Originally, it was a good thing, but it caused conflicts because of small things, involving a murder case, and Cai will eventually pay the corresponding price for his stupid behavior.
