Bai Jinxiu said in the letter that the day after she spread the letter from Li Mao, Li Mao entered the palace before the gates even opened. Considering Li Mao's cunning nature, he must have gone to see the Emperor first to confess about the letter.
Later, a fire broke out at King Liang's residence, and the Imperial Censor, Old Master Pei, impeached Left Prime Minister Li Mao. After Master Tan and Lord Shoushan closely compared the documents, they discovered the letter was forged. The new Minister of Judicial Review, Lu Jin, held onto it, and Left Prime Minister Li Mao was exonerated. Nonetheless, he still recuperated at home, and it seemed his son, Li Mingrui, no longer frequently visited King Liang's residence.
It seemed that the Li family held a grudge against King Liang, and the Emperor also became suspicious of Li Mao.
