This song started circulating among the people shortly after the late Emperor Chu Yin established the Da Ye Dynasty. Later, it was passed down as a prophecy song, said to predict that the dynasty would be replaced after three generations.
This naturally aroused the Emperor's displeasure.
It is said that at the time, many people named in accordance with the prophecy were implicated. Even Xiao Yuansui, reportedly because of his surname "Xiao", inherited the Marquis Poshan title, fitting the "Xiao Mountain" from the prophecy song, thus he gradually fell under the Emperor's suspicion and was not heavily relied upon.
After several purges, people named in accordance with the prophecy either died or fell into ruin, and this song gradually disappeared in the hustle and bustle.
But unexpectedly, it was brought up again now.
