In the development of the plot, the houses of Grandpa Song and Grandma Jiang were cheated away by two nephews, Kuang Anbang and Zhu Xingguo, and were controlled by them. They used various means to prevent Grandma Jiang from selling the house, which eventually led to the deterioration of Grandpa Song's condition and could not be cured.
After Grandpa Song and Grandma Jiang moved to a nursing home, their house was donated to the country. This ending was stipulated by Grandma Jiang in her will. She thinks this house should be owned by the state, not left to her two nephews.
This ending reflects the discussion of social morality and family ethics in TV series, and also reminds people to adhere to the principles of fairness and honesty when dealing with property and family relations.
