Of the bronze vessels discovered in 1976 when the Fu Hao tomb at Anyang was excavated, 190 were inscribed. The inscriptions were of 9 types. The most common, occurring on the most complete inventory of vessels, was the inscription Fu Hao (or Zi ), found on 109 vessels. The next most common was the inscription Si Tu Mu, occurring on 26 ritual bronzes, including one pair each of the square hu-jars, round jia-tripods, and round zun-beakers, one set of 11 gu-goblets, and one set of 9 jue-beakers. There was also a pair of large square zun-beakers inscribed with 4 characters, one line containing the characters Si Tu Mu, all written backwards, the other containing the character gui; including these there are 28 examples. The dating of these vessels is essentially the same as that of those vessels inscribed Fu Hao. It is very seldom that we find such a large number of vessels with the same inscription unearthed from the ritual bronze vessel horde of a single tomb. Bronzes with this inscription have been recorded since the Song dynasty and a bronze with this type of inscription was excavated from a Shang tomb at Xiaotun before liberation. There is also a bronze yue-axe with this inscription that currently exists. The study of this group of bronzes is very important.

In analyzing the inscription Si (Hou) Tu Mu Gui, one possible interpretation is that Tu Mu was the cognomen (Zi )of Fu Hao; another, is that it referred to a person close to Fu Hao in position. The inscription can be explained as Tu Mu, whose day name was Gui, or Mu Gui, whose name was Tu. She may have been another queen of Wu Ding, perhaps the Mu Gui sacrificed to in the Zu Geng and Zu Jia inscriptions, i.e., the Bi Gui who was the legitimate consort of Wu Ding in the Di Yi and Di Xin cyclical sacrifice records. Assuming this hypothesis is correct, then objects belonging to consorts Bi Xin and Bi Gui of Wu Ding have already been discovered. Since the discovery of the Fu Hao tomb, some scholars have put forth the theory that Mu Wu mentioned on the large inscribed Si Mu Wu ding-tripod may be Wu Ding's consort, Bi Wu. If the conclusions reached above can be established, then ritual bronze vessels belonging to all three of Wu Ding's consorts have been discovered. This fact is significant both for the study of the Shang ritual system and of the ritual bronzes.
