As a strategist with SJ, why did Liu Bowen have a bite of baked wheat cake before he died?

Speaking of this problem, first of all, I want to introduce Liu Bowen, who can be said to be the first strategist in later generations and is very clever. Then why did he eat such baked wheat cakes before he died? This actually has a lot to do with one of his predictions. He actually ate this sesame seed cake to remind Zhu Yuanzhang to get ready and prove that his prediction will come true.

Liu Bowen is a very powerful person. He not only strategizes, but also has a high military vision. He can pinch and calculate. Before that, Liu Bowen once made a prediction, called Pancake Song, which predicted what would happen 800 years later. The origin of this pancake song is a conversation between Zhu Yuanzhang and Liu Bowen. Zhu Yuanzhang ate a bite of sesame seed cake himself and covered it with a bowl. Then he asked Liu Bowen what was under this bowl, and Liu Bowen replied that there was food under it, saying that this food was bitten by a golden dragon. Zhu Yuanzhang admired Liu Bowen's skill, and then asked Liu Bowen what the Ming Dynasty would be like after 800 years. Liu Bowen knew Zhu Yuanzhang's character very well, so he asked Zhu Yuanzhang for a gold medal to avoid death, and then made a song "Cooking Songs" to predict what would happen in 800 years.

So I ate this sesame seed cake before I died, reminding Zhu Yuanzhang that his prediction would not go wrong, and I hope Zhu Yuanzhang will pay attention. After all, suggestions are generally unpleasant. What he said may be unpleasant, but it makes sense. I also hope that the emperor can believe his words and not doubt himself. If he only flatters the emperor, the country will never progress, so Liu Bowen is still very courageous.

In ancient times, when you were around the emperor, you had to be very careful. Your words may arouse the emperor's suspicion of you. People like Liu Bowen want the emperor to believe his prophecy before he dies, so they insist on eating baked wheat cakes before he dies.
