There are many treatises to be published since the Sui Gong Xu (<□公□>) has been announced which was bought by the Poly Art Museum in 2002. In my study, I try to explain the inscription on the Sui Gong Xu by a new viewpoint. That is through the intermediary of composition of article to explain the inscription anew. Besides to propose the etymological explanation to the words-「□」、「桼」in my study, I also compare the inscription with the Book of History (one of the Thirteen Classics (《尚書》))。The inscription is closest to〈無逸〉in the composition of article. Likeness to 〈無逸〉, the inscription had been written by the way of orderly composition: Yu-People (禹-民); Hou-ji-People (后稷『我王』一民); 「the nobility」-People (『貴族』-民). Under the composition, the inscription disclose that there is the probability that 「the nobility」 in the inscription is a king who was in the middle or late Western Chou. The gist of the inscription should be Sui-Gong exhorted the king to learn the Great-Yu and Hou-ji to be a great king.
