In the novel, I was Mr. Yin Yang for a few years... Was the story true?

As a fan of online literature, I must point out that the plot and characters of the novel "The Years I Was Mr. Yin Yang" are fictional and only exist in the novel. Therefore, whether this story is true or not depends on your definition of truth. If he was referring to whether the plot and characters in the novel existed in reality, then the answer was no. The profession of Master Yin Yang existed in Chinese history and legends, but it did not exist in reality. If it was referring to whether the time period described in the novel really existed, then it also depended on the definition of reality. The novel is a fictional art form that can create unique concepts of time and space. Therefore, whether the time period described in the novel really exists depends on your personal definition of reality.
