Episode 4 recap: Yu Qi Qiang, the captain of the medical team, fell ill.

Ma Jia officially joined the medical team for aid in Africa training. Here, he met new colleagues, including Yu Qi Qiang, the captain of the second African aid mission, Peng Wei, who was about to leave for Africa just seven days after getting married, and Wu Mei and Chang Lai, a couple who were going to Africa together. In order to quickly remember everyone, Ma Jia drew portraits of them during the self-introduction session and labeled their names on the drawings.

Peng Wei is a doctor from a children's hospital and is skilled at comforting children of all ages. After introducing himself, he performed a small magic trick for everyone. Ma Jia straightforwardly exposed the trick, but Peng Wei didn't get upset. While learning an African language, Peng Wei was amazed to see Ma Jia chatting with him and effortlessly remembering several words taught by their teacher.

Proudly, Ma Jia told Peng Wei that he was one of the few people who could multitask and automatically filter out useless information. Liu Xiao Xian worked late again today, and when Nannu saw her still busy after work, she invited her to have xiaolongxia (spicy crayfish) together. Liu Xiao Xian was excited while eating, but her mood changed when they got in the car. Faced with Nannu's inquiry, she bitterly complained about the overly selective taste of the current audience.

Nannu mentioned the "Tianhua Ban" program, which she worked on in the past. The proposal for the program was rejected more than ninety times, and she even had to let go of three staff members. It was only after countless hardships that the program came into existence. Liu Xiao Xian has always viewed this program as her goal. Seeing Nannu, who is much older than her, in such a good state, she sincerely admires her.

Nannu lifted her hair, and Liu Xiao Xian finally noticed that Nannu's hair had turned white. However, she not only exudes vitality and influences everyone around her, but also inspires Liu Xiao Xian to pursue what she wants and persevere. Jiang Yao learned that Xu Hui was at Luo Jin Sheng's art exhibition today, so she took Jiang Da Qiao to the exhibition, creating an opportunity for Jiang Da Qiao to interact more with Xu Hui. Ideally, Jiang Da Qiao would win Xu Hui back, leading to a happy reunion for their family.

Jiang Da Qiao lacks artistic sense. When he saw the painting on the wall, he thought the purple color was lavender, but he was surprised to learn that it represented a purple sky. Luo Jin Sheng affectionately explained that he painted it because Xu Hui had dreamt of a purple sky. Jiang Da Qiao felt a bitter pang in his heart, believing that he shouldn't disrupt Xu Hui's current happy life. He remained silent, refusing to join Jiang Yao for a family dinner. Instead, he let Jiang Yao go and have dinner with Xu Hui and Luo Jin Sheng. This angered Jiang Yao, and she quickly left, leaving Jiang Da Qiao and Xu Hui to have a private conversation.

Xu Hui mentioned Jiang Yao's intention to move in and live with Jiang Da Qiao. Jiang Da Qiao thought it was a good idea, but Xu Hui felt that Jiang Yao had her own thoughts. Seeing that Jiang Da Qiao not only supported Jiang Yao but also offered to help her move her things, Xu Hui suddenly became angry and accused Jiang Da Qiao of neglecting Jiang Yao for so many years. However, she quickly realized that she had overreacted and turned away, feeling sad.

Feeling guilty, Jiang Da Qiao didn't know what to say. They stood back to back, while Jiang Yao watched from a distance, filled with disappointment. The training for the aid team in Africa would end in one more week. Based on everyone's performance and skills during this period, Yu Qi Qiang assigned part-time roles to everyone. Ma Jia, being skilled with a knife, was appointed as the barber responsible for cutting the hair of male colleagues. However, it was Ma Jia's first time doing such a task, so he quickly called Chang Lai to practice. At first, using a ruler, Ma Jia shaved without any issues. But later, relying on his sense of touch, he accidentally shaved two bald patches on Chang Lai's head. To fix it, he had to shave a pattern, and it turned out to be two turtles. Chang Lai was mocked by classmates during class.

During a class, Yu Qi Qiang suddenly experienced aortic dissection. Ma Jia made a timely judgment and sent Yu Qi Qiang to the hospital. He personally performed the surgery, which was highly successful. When Yu Qi Qiang's spouse learned about it, they expressed special gratitude to Ma Jia. However, Yu Qi Qiang could no longer return to San Na. This was extremely bad news for Yu Qi Qiang, who had a deep emotional connection to San Na. Given his current health condition, it seemed hopeless for him.

Jiang Da Qiao had previously stayed in San Na Meile Village with Yu Qi Qiang, so he understood Yu Qi Qiang's emotional attachment to San Na and felt regretful for him. Meanwhile, a heated argument erupted in Liang Sen Lin's office. The reason was that Yu Qi Qiang, the team captain, fell ill, and an experienced doctor was urgently needed to lead the team. The leadership suggested Jiang Da Qiao, but Liang Sen Lin firmly refused. He knew well that Jiang Da Qiao had spent years away from his family, and now that he had finally returned to live with his daughter, he didn't want to disrupt Jiang Da Qiao's newfound happiness. Unexpectedly, Jiang Da Qiao overheard the conversation outside the door.
