What does the waving sweet potato mean?

Hot potato According to the Chinese dictionary of the Ministry of Education, "sweet potato" is another name for sweet potato, which is usually scalded with boiling water, so it is very hot when it is just cooked, and no one can hold it. Therefore, "hot potato" is likened to a thorny matter that all parties are unwilling to take over. The word "hot potato" cannot be tested today. However, there are some folklore related to Zhu Yuanzhang, the Ming emperor, which is related to this word. According to folklore, after he became emperor, two childhood playmates went to see him, hoping to get some benefits from his childhood friendship. When three people met and talked about childhood, one of them talked about the past when he was hungry and picked up a broken crock by the roadside to cook boiled sweet potatoes. It was warm. As soon as Zhu Yuanzhang's face fell, he ordered someone to drag him out and behead him. Later he asked another person to "explain the past clearly". The rest of the people are trembling, talking about the past of "tackling the problem of Zhoucheng and capturing General Yu alive (impression)". Zhu Yuanzhang gave him one hundred and twenty when he heard the dragon heart. This story shows that "hot potato" is really not for everyone to bear.
