Which one of the following would not be considered one of the major sources for studying the Shang Dynasty?

One of the major sources for studying the Shang Dynasty is oracle bone inscriptions, which provide insights into their writing system and religious practices. In contrast, modern fictional accounts or interpretations, such as novels or movies about the Shang, would not be considered a major source for historical study, as they often prioritize storytelling over factual accuracy. Thus, fictional works would not serve as reliable sources for understanding the Shang Dynasty.
