Discoveries of Hwangnyongsa-style metal belts, usually brackets and belts as well as round and edge ornaments, excavated from the lower part of the pillar built in the center of this wooden pagoda in Gyeongju led the existence of this site to become known. Subsequent excavations have intermittently targeted local burial tombs but few cases have so far been found; it is nevertheless important to carefully consider the appearance, development, and extinction of these tombs as occurrences are only known from a limited time period between the late sixth century and early seventh century. One characteristic feature of Hwangnyongsa-style metal belts is that the ornament and the pattern are raised together; this means that when a belt is worn it buckled by inserting a bracket needle into a round ornament. This is different from the inverted leap-like shape of a metal belt and somewhat similar to the way that these items are depicted as being buckled in Chinese burial mound and mural figures. Most of the patterns seen on these metal belts are also shared with decorative designs seen on reliefs and murals from North dynasty and Sui dynasty ancient tombs; on this basis, these artifacts can be viewed as Chinese-influenced Silla metal belts. Hwangnyongsa-style and Tang-style metal belts have also not been differentiated from one another in conventional interpretations and it has been considered reasonable to assume that the method of ornament making innovatively changed from the use of patterns to none. Hwangnyongsa-style metal belts can therefore be included within the same category as their Tang-style counterparts, as part of the evolution of these items in China. It is known that the Silla dynasty formed political ties with the Chinese dynasty at some point during the middle of the sixth century via the tributary appointment system. This led to a transformation of cultures and products inside China to fit the situation within the Silla dynasty which was then utilized for regional control; the Silla dynasty ruled rural areas by providing Oewie to local forces newly incorporated into the area and by including numerous local owners into the Gyeongwie system subsequent to unification. The time between the mid-sixth century and the early seventh century when the Oewie system was functioning within the Silla dynasty therefore functioned as a tool for regional control and is consistent with the timing of the appearance of Hwangnyongsa-style metal belts in rural areas and changes in their form.
