Test and analysis: The cultural relic shown in the picture is Oracle Bone Inscriptions, which appeared in Shang Dynasty and is the earliest writing in China. Its excavation provides important information for studying the development history of Chinese characters. Therefore, it is obviously wrong to choose item B, so we can study the history of Shang Dynasty. Error C, Oracle Bone Inscriptions is not a piece of paper, but the words are engraved on the tortoise shell bones; D Error, Oracle Bone Inscriptions is still a practical writing, which has not developed to the stage of calligraphy.
Comments: This question examines basic historical knowledge. Calligraphy developed into a conscious art in Wei, Jin, Southern and Northern Dynasties. There were the earliest symbols in the Neolithic Age. The Shang and Zhou Dynasties were mainly Oracle Bone Inscriptions and Jinwen. During the Qin and Han Dynasties, Xiao Zhuan and Han Li had a preliminary aesthetic feeling. In addition, we should also know that calligraphy is an integral part of China traditional culture, and with the help of proper density of Chinese characters, we can write aesthetic feeling.
