摘要: At the beginning of the 20th century, a large number of bamboo and silk manuscripts in the Han Dynasty were excavated, together with newly unearthed bronze and stone inscriptionsin which further deepened people's understanding of characters in previous eras, To a certain extent, it further verified the defined characteristics specific to strokes of Han official script based on epigraphy, such as, “start like a silkworm head and end like a swallow tail”, “wavelike leftfalling stroke and rightfalling stroke as Zhe” However, the beauty of the typical official script strokes came into being in steps, not all at once, Specifically, the formation process of “Bozhe”, as a symbol of mature strokes, was closely related to many influencing factors throughout its development process, such as the innovation of writing materials, the evolution of the characters themselves, etc. An in-depth analysis of this issue could not only help enrich the development path of wave formatio, but also deepen the understanding of formal beauty of Chinese characters.
