Source: "The Biography of the Ram Ding Gong Thirteen Years": "This is a villain on the monarch side." Tang Li Shangyin's poem "Feeling": "There was a clear monarch in ancient times, but there is no shortage of years now." "The Biography of Chou Shiliang in the New Tang Dynasty": "Treacherous officials are difficult to control, and they swear to the death to clear the monarch."
