When King Wen was the crown prince, he went to court with King Ji at three o'clock in the morning. When the cock first crowed, he dressed and went to the door of the bedroom. He asked the eunuchs, "How are you today?" The eunuchs said, "All right." King Wen was happy. At noon, he came again, and did the same. At dusk, he came again, and did the same. If there was any irregularity, the eunuchs would tell King Wen, and King Wen looked worried and could not walk straight. King Ji had a meal, and then he returned to the beginning. When the food was on top, it must be on the spot. He looked at the cold and warm rhythm. When the food was down, he asked what the meal was. He ordered the chef to say, "Is there a source at the end!" The answer was, "Yes." "Then they withdrew. King Wu led the way and dared not add anything. King Wen was ill, but King Wu did not take off his hat and belt to nurse him. When King Wen ate once, he also ate once; when King Wen ate twice, he also ate twice. After ten days, they stopped. King Wen asked King Wu, "What did you dream about?" King Wu replied, "I dreamed that the emperor and I were nine years older." King Wen said, "What do you think it was?" King Wu said, "There are nine countries in the west. Will the king finally rule them?" King Wen said, "No. In ancient times, age was called age, and teeth were also age. I am a hundred and you are ninety, so I am three of you." King Wen died at the age of ninety-seven, and King Wu died at the age of ninety-three. King Cheng was young and could not ascend the throne, so Duke Zhou became his prime minister and ruled the country.
