Episode 24 recap: The First Brigade deeply mourns the marriage of Wu Qiang Zhang Biao and Wang Lan Zhi.

Luo Xiang Qian, suppressing his grief, performed a fast-paced recitation on stage. As he spoke, tears streamed down his face. Memories of the moments he had spent living and working with Wu Qiang flashed before his eyes. The solemn expression of the brigade commander affected everyone present, and they unconsciously stood up together. Luo Xiang Qian informed the higher-ranking cadres of Wu Qiang's sacrifice. Wu Qiang's sacrifice had caused the party to lose a loyal soldier, and the First Brigade had lost an intimate comrade and brother. Luo Xiang Qian took out the button left by Wu Qiang and called on the road construction army to turn their sorrow into strength, inherit Comrade Wu Qiang's aspirations, and quickly complete the Chengdu-Chongqing Railway.

The cadres and soldiers of the First Brigade bowed three times to the button of Wu Qiang, wishing him eternal glory. Seeing the young child and Zhang Biao playing happily, Luo Xiang Qian urged Zhang Biao to quickly report to the superiors and marry Wang Lan Zhi. Captain Ma held an advanced commendation meeting in the First Brigade and fully affirmed the work of the brigade.

Those who were recognized as advanced personnel went on stage wearing big red flowers, and Ye Lan, representing the exemplary models, delivered an acceptance speech. Captain Ma also brought a film projection team and played the movie "The White-Haired Girl" for everyone. Many people watched a movie for the first time and were therefore extremely excited and fully engaged. Captain Ma had to return to the support team overnight, and Luo Xiang Qian asked him to pay attention to safety.

When Young Wa saw the landlord being arrested, he suddenly stood up and said that his father had been taken away like that. Sha Kai, upon hearing this, questioned Young Wa vigilantly. Wang Lan Zhi quickly covered Young Wa's mouth. At this time, others were discussing and saying that it turned out the First Brigade was still harboring counter-revolutionaries. Luo Xiang Qian came over to stop everyone from casually discussing and said that they should wait until the situation is thoroughly investigated before making any conclusions.

Wang Lan Zhi took Young Wa and ran back to the dormitory to pack their belongings and prepare to leave. Ku Mei came to stop her, but Wang Lan Zhi said she could only leave with her child to avoid causing trouble for Zhang Biao. Ku Mei asked Wang Lan Zhi to go to her house first to hide, and then she would find a solution for her. Luo Xiang Qian learned that the man Wang Lan Zhi had previously married was a counter-revolutionary, making Wang Lan Zhi a relative of counter-revolutionaries. Zhang Biao was a cadre and also the subject of the party organization's investigation, so it was necessary to clearly draw a line between Zhang Biao and Wang Lan Zhi in this regard.

Zhang Biao did not return all night as he went to find Wang Lan Zhi. Luo Xiang Qian found Ku Mei and discussed the seriousness of the situation, urging her to reveal everything she knew. Hearing this outside the door, Zhang Biao hurriedly rode his horse to Ku Mei's house to find her. However, Wang Lan Zhi refused to open the door to see him as she didn't want to further impact Zhang Biao. She felt that she had to leave the brigade.

But Zhang Biao expressed that he would rather not go back and stay with Wang Lan Zhi. Wang Lan Zhi advised him not to become a deserter and to continue working on road construction with the brigade. Zhang Biao insisted that Wang Lan Zhi should go back with him and clarify the situation with the organization. Otherwise, when would she hide with their child? After hearing this, Wang Lan Zhi silently opened the door.

Ku Mei told Luo Xiang Qian and Doctor Yu about Wang Lan Zhi's story. She had been sold to the landlord's family because her father had debts. It was only after the government suppressed that person after the liberation that Wang Lan Zhi was able to free herself from his control. Luo Xiang Qian believed that Wang Lan Zhi couldn't be considered a landlord's wife, but others might not see it that way.

Doctor Yu said that the impact of this matter was not good. The poor workers who had been oppressed by the landlords in the brigade directed their anger towards Wang Lan Zhi. Therefore, it was necessary to handle the situation carefully and promptly. Luo Xiang Qian arranged for Doctor Yu and Technician Ye to work on the workers' ideology, while he himself took Ku Mei back to her home to find Zhang Biao and Wang Lan Zhi.

When Luo Xiang Qian saw Zhang Biao, he launched into a torrent of criticism and reprimands. However, he was surprised to learn that Zhang Biao didn't want to desert but intended to bring Wang Lan Zhi back to the brigade headquarters to explain the situation. Ye Lan brought some preserved fruits sent by her mother for Luo Xiang Qian but also criticized him for not showing enough concern for his comrades and for his rough work style.

After Ye Lan left, Luo Xiang Qian carefully pondered her words and realized that he hadn't been doing well enough. He specifically called Zhang Biao and Wang Lan Zhi together, with comrades like Ye Lan as witnesses. He first apologized to them and then announced the order from the higher-ups, agreeing to Zhang Biao and Wang Lan Zhi's marriage. Zhang Biao and Wang Lan Zhi were ecstatic upon hearing this. They expressed immense gratitude to Luo Xiang Qian and the comrades of the First Brigade. Zhang Biao vowed to work even harder and make new contributions to the construction of the Chengdu-Chongqing Railway.
