《史记·三十世家·三王世家》
我不胜犬马之心，冒死上疏进言，希望陛下命有司，趁盛夏吉日早定皇子之位。
臣窃不胜犬马心，昧死原陛下诏有司，因盛夏吉时定皇子位。
With the loyalty of a dog or a horse, I risk my life to present this memorial, and hope that your Majesty would order the relevant authorities to settle the matter of the princes' status on an auspicious day in midsummer.
