We can speculate that there are probably two reasons for naming the two brothers by turning the word "peace" upside down. One is that when naming the elder brother, he did not know that there would be a younger brother. It will give people a sense of reality. The other one is upside down, which also means that the two brothers' lives are not peaceful.
You must know that the two brothers were not born together, so as parents, when naming their children, they would not name their children in the order of Ping An. Then, when the eldest son is born, the family may name him in the hope that he will be safe and secure throughout his life. So out of this consideration, An can represent something better than Ping. But when the second son was born, he would want to make up a word for the two brothers. At this time, the younger son was named Ping. It is not surprising that the combination of the two brothers means peace. Moreover, when naming the protagonists in the article, most novels will name the two brothers with words like Wenwu. So in this article, the names of the two brothers are reversed in an anti-traditional way, which seems to get rid of the usual naming in novels. That kind of dramatic arrangement.
In addition, the ending of the two brothers in this novel is not very happy. For example, Shaoan, although he failed to marry his first love Runye, his daughter-in-law Xiulian was able to survive. Live a down-to-earth life with him. If his wife had not died, Shaoan would have been stable for the rest of his life, but the novel gave him an incomplete ending. After Shaoping became a worker, his love with Xiaoxia developed particularly beautifully, but later Xiaoxia died in a flood, and Shaoping lost hope for the future.
So, the author reversed the names of the two brothers. One reason is to go against the traditional naming method in novels, and the other reason is that the ending of the brothers is not as peaceful as their names.
