"It is my duty to share the worries of His Highness the Crown Prince."
"Oh? Since General Lu said so, I really have something to do today and I would like General Lu's help."
"Your Highness, please speak."
"Since the day of the general's expedition, I have often had trouble sleeping alone, so I would like to ask General Lu to help warm the bed."

The next day, the young eunuch who called His Highness the Crown Prince to have an early morning session quietly asked the Duke: "Grandpa, why did General Lu sleep with His Highness the Crown Prince? This is... Bed climbing."
"Go, go! How can this be called climbing on the bed? This is called sacrificing one's life for the country!"
