Broadly speaking, these written materials are of great significance to archaeology and calligraphy.
The study of ancient characters, bamboo slips and Oracle Bone Inscriptions belongs to the category of ancient philology.
Because the inscriptions span a very wide age (from the earliest existing Taishan stone carvings to modern times), the books used are also very complicated. Except for some early inscriptions on ancient Chinese characters (mainly Qin Zhuan), it is of little significance to the study of ancient Chinese characters. However, it is of great value to the research fields of calligraphy, literature and history.
In archaeology, stone carvings (mainly inscriptions on bronzes and pottery, excluding rubbings), bamboo slips and Oracle Bone Inscriptions are of great value to the dating study of early history and related cultural and historical events. Ancient philology, the main purpose of which is to study its meaning interpretation and text structure, also belongs to a branch of archaeology.
