What are the artistic features of bronze inscriptions used in the early Zhou Dynasty?

Bronze inscriptions used in the early Zhou Dynasty are similar in strokes and structure to Oracle inscriptions in Yin ruins. After Wang Zhao, the inscriptions on bronze in the Western Zhou Dynasty became more and more mature. Representative works include Wang Zhao's Zong Zhou Zhong and Gong Wang's wallboard. At this time, the main characteristics of inscriptions on bronze are as follows: the strokes are gradually rounded from the shape of tadpole tail, and most of them are round; The knot is more upright, tighter, more stable and more regular than the bronze inscriptions in the early Zhou Dynasty. In composition, I began to pay attention to vertical and horizontal spacing and line spacing. The inscriptions with boundary grids are more rigorous, while those with larger spacing and row spacing are very sparse and open.
