Episode 22 recap: Jia Jin Long provided clues to Wang Xin to find the child.

Ma Yan stole a letter written by Yao Yu Ling, opened it at home, and glanced at it. He found out that it was a letter from Yao Yu Ling asking Wang Xin to reconcile. Yao Yu Ling explained that when she broke up with Wang Xin, it was a moment of confusion, but now she regrets it and sincerely hopes that Wang Xin will come back. Yao Yu Ling saw Wang Xin leaving early in the morning, so she followed him to see his response after reading the letter. Wang Xin told Yao Yu Ling about the letter and said he was deeply moved by it. He also mentioned that he couldn't let go of the past before, but now he has moved on and thanked Yao Yu Ling for wishing him and Ma Yan well. Wang Xin's intention is clear; he wants Yao Yu Ling to know that their relationship is over, and now he only wants to be with Ma Yan.

Shen Xiu Ping woke up early and found herself at Ma Kui's house. Feeling embarrassed, she wanted to leave, but unexpectedly, she ran into Ma Kui at the door while he was sweeping. After an awkward greeting, Shen Xiu Ping left and was seen by Lu Hong Xing, who was pouring a chamber pot. Lu Hong Xing assumed that something was going on between Shen Xiu Ping and Ma Kui, so she went home and discussed it with her husband, Lu Hong Xing, but he advised her not to spread gossip.

Liu Gui Ying started kidnapping children again. This time, she chose a busy moment when passengers were getting on and off the bus, quietly taking away a child without the passengers' knowledge. Captain Jiang held a meeting to discuss catching human traffickers, and Wang Xin immediately requested to go to Ha City to catch the trafficker. He believed that the trafficker in Ha City this time was the same person he encountered before, and he needed to redeem himself.

Wang Xin volunteered to go to Ha City to catch the trafficker. As Wang Xin's master, Ma Kui could only request to accompany him. On the way to Ha City, Ma Kui also brought snow boots to a blind man on the roadside and had a conversation with Wang Xin about their past. The bond between master and disciple grew stronger.

Ma Kui and Wang Xin settled down in Ha City and began searching for the trafficker the next day. Unexpectedly, they stumbled upon a group of people beating someone and had to step in to stop them. However, the group didn't differentiate between right and wrong and started attacking Ma Kui and Wang Xin. In the end, they even brandished knives. Outnumbered and facing armed assailants, Ma Kui and Wang Xin had no choice but to escape and hide for a while. When they saw that the people had dispersed, they wanted to leave but coincidentally brushed past Jia Jin Long, who immediately recognized them, although they didn't recognize him.

Seeing that Ma Kui and Wang Xin were being harassed by the thugs in Ha City, Jia Jin Long stepped forward to help and lied, claiming to know Teng Lamei, which scared off the thugs.

After Jia Jin Long helped them, he mentioned the incident on the train years ago when they encountered the robbers selling roasted chicken. They realized that they had encountered an old acquaintance when they were rescued by Wang Xin.

After returning to the hotel, Wang Xin started chatting with Ma Yan, but their conversation was interrupted when Ma Kui hung up the phone. Ma Kui once again expressed his disapproval of Wang Xin being with Ma Yan, not because Wang Xin is not good, but because their families are not compatible.

After criticizing Wang Xin, Ma Kui went to Peng Ming Jie's house to visit him and inquire about the human traffickers. Without prior notice, Ma Kui went to Peng Ming Jie's house and happened to catch Peng Ming Jie accepting bribes. Ma Kui kindly advised Peng Ming Jie not to be manipulated by others.

After Ma Kui left, Wang Xin called Jia Jin Long to ask about the human traffickers and coincidentally learned about the possibility of the child being in Laogou. When Ma Kui returned, Wang Xin informed him about the situation, but Ma Kui scolded Wang Xin again, blaming him for not informing him in advance.

After criticizing Wang Xin, Ma Kui decided to investigate the situation in Laogou and discovered that the person selling the child there was likely Liu Gui Ying. Jia Jin Long provided valuable information, so Ma Kui and Wang Xin invited him to have a meal to express their gratitude.

Before leaving, Jia Jin Long gave Ma Kui and Wang Xin a bag of local products each. Despite their attempts to refuse, they couldn't reject Jia Jin Long's goodwill and accepted the gifts. Peng Ming Jie visited Ma Kui's house, and Ma Kui wanted to bring out the liquor he had stored for twenty years, but he couldn't find it.

Ma Yan lied, claiming that Ma Kui might have already consumed the liquor and couldn't remember where it was. Peng Ming Jie brought a sheep, and Ma Kui couldn't help but remind him that as a leader, he should know what is right and wrong and avoid bribery.

Ma Kui and Peng Ming Jie had a joyful drinking session, and Ma Kui invited Peng Yong Li to stay at his house. He even asked Peng Yong Li to consider him as his godfather, strengthening the relationship between their families. After Peng Ming Jie left, Ma Kui made arrangements for Peng Yong Li to stay at their home and asked Ma Yan to take care of him. He also occasionally questioned Ma Yan about whether she had given his liquor to Wang Xin.

In the blink of an eye, it was the Spring Festival of 1984. The passenger volume on the railways had increased significantly, and the pressure on the railway department was immense. Everywhere was crowded with people.
