The author mainly wants to remind parents to provide their children with a living environment in yowza and get more ideological education at the same time. No matter how much wealth, diligence, economy and hard work are also important, and sustainable development is king.
However, in addition to the author's point of view, I also see that the hero of the story, Zheng, is optimistic by nature. After his life changed greatly, he didn't choose to die, but he wanted to live even though he begged. Through this incident, I understand that as long as you are alive, there is hope, and people will encounter many difficulties in their lives, but as long as you work hard to overcome or adapt to adversity and find a way out, there is always a chance to turn over.
