It tells us that my father raised us, but now we have left our hometown because of our work and lack of love for our parents. My father used to take good care of us and accompany us in every process of our growth. Now the hourglass of time is reversed, and my father has become an empty nest old man. Therefore, the work calls on us to go home often. Reflects the Chinese culture of filial piety. Filial piety comes first.
