《周书·本纪·卷一》
王氏醒后告诉德皇帝，德皇帝高兴地说： 虽然没有到达天上，尊贵也到极点了。 太祖出生时，有像盖子一样的一团黑气，向下覆盖住他的身体。
寤而告德皇帝，德皇帝喜曰： 虽不至天，贵亦极矣。 生而有黑气如盖，下覆其身。
After Wang woke, she told De Emperor, De Emperor happily said: "Although did not reach heaven, this is the greatest honour." When the Great Ancestor was born, there was a black cloud that covered his body like a lid.
