Li Senxiang told the outline of the story in the third person.

Father always feels that his steps are low and always envies others' high steps. Not wanting to be inferior to others, he made up his mind to build a new house with high steps. After a long period of preparation, he finally built a new house with nine steps. In my life, my father's lifelong wish has come true. He is very happy, but he has paid the price of the completion of a new house, the aging of people and the collapse of his body.
