Who knows the legend of Liu Xiufen?

It is said that Liu Xiu's son is very disobedient, and he is always against Liu Xiu when he is told to go east and west. Liu Xiu wanted to be buried in the Phoenix Mountain above Beimang before his death, so he deliberately said it backwards before he died and ordered him to be buried by the Yellow River. I didn't expect this disobedient son to be obedient once, and he was buried by the Yellow River according to his father's instructions. Although this legend is a folk explanation that ordinary people can't explain the unique position of the original mausoleum, it adds a mystery to the original mausoleum. After all, there is only one emperor lying on the edge of the Yellow River throughout the ages.
