Ma Jia eagerly awaited the arrival of the mainland delegation of visiting relatives. Among his closest family members were his teacher, Principal Liang, and his wife, Liu Xiao Xian. Liu Xiao Xian, feeling resentful and caught in a cold war, had been solely responsible for taking care of Ma Jia's father during his surgery and was unfairly blamed for any complications that arose.

Later, Ma Jia faced obstacles and suppression throughout the hospital, which compelled him to consider changing jobs. Principal Liang did not intervene or try to retain him. Moreover, Jiang Da Qiao also requested assistance in Africa, knowing well that the two of them were not compatible and that there was no need for both of them to be key members in two different departments. Principal Liang did not speak up or take the initiative to keep Ma Jia.

When they arrived in Africa, Ma Jia saved lives, almost contracted HIV, but Principal Liang did not offer any consolation. Ma Jia was extorted by a taxi driver, and during a Mid-Autumn Festival banquet in a foreign land, Principal Liang called without any pleasantries, without understanding the situation, and immediately began accusing him of causing trouble. In the end, Jiang Da Qiao was favored over Ma Jia, not only in terms of professional competence but also in terms of family responsibilities.

The problems faced by Ma Jia and Liu Xiao Xian are common among members of medical aid teams in Africa. Long-distance separation between spouses leads to various feelings of loneliness, loss, and difficulties. It is a conflict between family and career that not only Ma Jia but also Doctor Su Xin and even Jiang Da Qiao faced, resulting in Jiang Da Qiao divorcing during his first aid mission.

However, Jiang Da Qiao's lack of family responsibility may be even worse. His daughter, Jiang Yao, is always either throwing tantrums or on the verge of doing so. But Jiang Da Qiao, on the contrary, is overly affectionate and proactive, more so than in the past year, taking the opportunity to flaunt his love and disregarding his daughter's feelings.

It is difficult to imagine if Ma Jia were Jiang Da Qiao, with average abilities and a chaotic family situation, and had even been involved in medical accidents. Even if he participated in aid missions in Africa or Tibet, would he have the chance to become a team leader or a director and achieve a high professional position? The answer is clearly no. Principal Liang could have late-night conversations with Jiang Da Qiao, discussing and evaluating Ma Jia calmly and as a friend.

However, Principal Liang rarely had a genuinely calm and personal conversation with Ma Jia. Instead of criticism and reproach, it was perplexing that he hardly spoke to him in a heartfelt manner.
