What's the secret that Liu Bowen wanted to eat a sesame seed cake before he died?

Liu Bowen is a man who worked with Zhu Yuanzhang. He was born in the Yuan Dynasty and is very clever. When he started to be an official, he felt that the corruption in the imperial court was deeply rooted, so he resigned and retired. Later, I was introduced to Zhu Yuanzhang and gained his appreciation. It was a famous think tank around Zhu Yuanzhang who gave him advice.

According to legend, Liu Bowen is a man who knows what's going on in the world, that is, a man of God like Zhuge Liang and Jiang Ziya, who can predict the future. Personally, I think this is the apotheosis of his descendants. Maybe he is just smart and far-sighted. But the pancake song he wrote is really full of magic, which has aroused the infinite reverie of future generations.

Legend has it that one day when Zhu Yuanzhang was eating sesame cakes, he buckled a piece of cake he had bitten with a bowl. Estimation is to test whether Liu Bowen is really as powerful as the legend, so let him know what's in his bowl. Unexpectedly, Liu Bowen said, "The things in your bowl are like the sun and the moon, and they were bitten by a real dragon." The real dragon refers to Zhu Yuanzhang, and he doesn't forget to kiss up. This surprised Zhu Yuanzhang and lamented Liu's miraculous powers. So he went on to ask him how lucky the Ming Dynasty was, and how long it took to talk about the collapse of his country in front of the emperor, but it was easy to lead to death. After winning the gold medal of Zhu Yuanzhang's exemption from death, he predicted that there would be a phenomenon of brothers coming down in the Ming Dynasty, and Daming had more than 200 years of luck.

Later, Liu Bowen was excluded from the DPRK, Zhu Yuanzhang loved to kill heroes, and Liu Bowen resigned and went home. Before he died, he wanted to eat a sesame seed cake, perhaps to remind the emperor or the world that the predictions in his baked songs would come true one by one. Later, these bold predictions did come true, but I still think this may be just a gimmick made by later generations to show Liu's magic.
