What was the first masterpiece in its heyday?

In its heyday, the works of this period were originally represented by Lu Gui, and there were many excellent works at that time, such as Gui Qi Ming, Shi Kui Fu Ding Ming, Jiu Nian Ming and so on. Pan Pan Ming is a typical representative of bronze inscriptions in the Western Zhou Dynasty. The purification of its lines and the order of its structure have reached a high level, with rounded lines, symmetrical structure and pure breath. The last line of the inscription has five more words than other lines, which is slightly crowded, which is its deficiency. Those that appeared together with the inscriptions on the disc, but later appeared, such as the inscriptions on Zhong Xing and Gui Xing, were more strictly incorporated into the specification in structure than the inscriptions on the disc. Especially in Zhuizhuixing Ming, the vertical and horizontal parallel lines became the dominant, and its parallel and orthogonal structure paved the way for Ding Ming Fu and Hu Ming Fu. During this period, Ding Ke's size was also a classic inscription of the Western Zhou Dynasty. Daming was unearthed in Fufeng County, Shaanxi Province on 1890 and recorded by epigraphy calligrapher Wu You. This work clearly retains the square grid drawn for the standard grade, and the text is written in the drawn grid.
