《北史·列传·卷三十五》
由此可以知道明堂共有五室，这是尧、舜、禹三代都一样的。配上帝王的肖像和事迹，意义就很明白了。
是知明堂五室，三代同焉，配帝像行，义则明矣。
From this, it can be known that the Mingtang has a total of five rooms, and this was the case for the three dynasties of Yao, Shun, and Yu. Paired with the portraits and deeds of emperors and kings, the meaning is clear.
