Xu Chengfeng and his wife lived under an AA-split system for thirty-five years, silently enduring misunderstandings and always remaining self-reliant and strong. However, his wife secretly transferred a large amount of income to her sister, and before retirement even transferred the property for one yuan, attempting to monopolize the benefits. On the day of retirement, she demanded that Xu Chengfeng be a full-time househusband, and he calmly handed over the divorce agreement, defending his rights according to the law, neither arguing nor snatching, seeking only fairness and dignity. After the divorce, he continued to devote himself to industry and scientific research, established an education fund to support engineering students, and interpreted integrity, struggle, and responsibility with his actions. Facing the past, he chose to let go, rebuilding his life with rationality and kindness, and finally ushered in a new beginning in career and emotion.
