Niu Dali asked someone to buy a second-hand TV at a high price. He happily sent it to Yao Yuling, but the TV could not be turned on. Niu Dali had to take it for repair. Only then did he realize that except for the outer shell of the TV, the parts inside were intact. They were all broken. Niu Dali was very worried. This TV cost him a year's salary. He was unwilling to give up and had to come to Wang Xin for help.
Wang Xin came to the seller pretending to be a customer buying a TV. The seller gave him an identical TV. Wang Xin showed his ID card and caught the man on the spot. Cases of theft of rail fasteners have been frequent recently, and the leader asked police officers to patrol in pairs. Neighbors sat in the yard watching TV every night. They discussed while watching, and laughter filled the yard. Yao Yuling did not want to join in the fun, so she had to entertain herself at home.
At night, Ma Kui and Wang Xin were ordered to squat along the railway line in Xiaoli Village. Wang Xin wore too few clothes and he was shivering from the cold. Thanks to Ma Kui's preparation of cotton mattresses in advance for Wang Xin to keep out the cold, they kept watch all night. There was no sign of the thief, so they had to call it a day and go home. Ma Yan gave Wang Xin a kettle.
Cai Xiaonian and his girlfriend confirmed their relationship, and they began to talk about marriage. The girl's mother asked for 48 legs and eight Phoenix bicycles to pick up the bride. Cai Danian and Cai Xiaonian were so anxious that they had no choice but to discuss countermeasures with their neighbors. They were helpless. Wang Yongge asked Cai Xiaonian talked to his future mother-in-law. Ma Kui and Wang Xin squatted in the woods next to the railway track, but still found nothing.
Cai Xiaonian went to negotiate with his future mother-in-law, but she refused to let go. Cai Xiaonian had to go back to the neighbors to discuss countermeasures. Wang Xin persuaded Cai Xiaonian not to give in. Ma Yan laughed at Wang Xin and couldn't find a wife in the future. Yao Yuling kept claiming that as long as the man treats her well, everything else It didn't matter. Niu Dali also sided with Yao Yuling. Ma Yan sneered at them both. Yao Yuling and Ma Yan had a fierce argument when they disagreed, and finally broke up.
Lu Hongxing came up with the idea to ask neighbors to help assemble 48 legs. Cai Xiaonian and his girlfriend each provided four bicycles. Cai Xiaonian hurriedly went to discuss with his future mother-in-law. Ma Kui and Wang Xin squatted on the railway in Lijiacun for several days, but found nothing. Wang Xin decided to go reconnaissance for a long time. Ma Kui advised him not to do useless work, but Wang Xin did not listen at all. Wang Xin came to the railway track and squatted down. He saw someone approaching from a distance. He thought it was a thief. Unexpectedly, the person was Ma Kui. Ma Kui believed that the thief would not commit crimes during the day and forcibly took Wang Xin away.
The thief stole the rail fasteners at two o'clock in the afternoon and was discovered by the villagers. Captain Jiang told Wang Xin and Ma Kui about the incident, and Ma Kui realized that he had been negligent. He wanted to take Wang Xin to stay at home, but the old disease relapsed, and Wang Xin sent him away. At the hospital, Shen Xiuping reminded Ma Kui to take good care of himself, otherwise he would have to undergo surgery, so Ma Kui had to be obedient.
Ma Kui recovered and was discharged from the hospital. He took Wang Xin to stay in the area. From a distance, he saw someone riding a motorcycle to steal the rail fasteners. Wang Xin stood up and confronted the thief. He was so frightened that he ran away. Ma Kui gave Wang Xin his bicycle. Xin went to chase the thief on his motorcycle, but the thief fell to the ground on his motorcycle. Wang Xin captured him alive, and Ma Kui took the tools to repair the rails.
