Book of Seeking Zhouyi and Shangshu

If you want to study the book of changes, which does not involve astrology and divination, I recommend an introduction to the book of changes, which contains the original text and Chen's comments. If mathematical mathematics is involved, please read Shang's Study of Zhouyi, or Guo Yao's Zhonghua Book Company's Notes on Zhouyi. Shangshu also suggested Zhonghua Book Company Edition. After all, the books of Zhonghua Book Company are more authoritative and have fewer mistakes. You can buy an annotated version of Shangshu by Professor Mu Ping from Zhonghua Book Company. If Shangshu wants to see a large-scale annotated edition, I recommend Shangshu Zheng and Zeng Yungan published by China Normal University Press, which is a beginner's edition. If the research is more in-depth, I recommend Shangshu Guwen Shu (the first and second volumes of this collection), and Yan Ruoqu's works are published in Shanghai Ancient Books Publishing House. If this answer is helpful to you, I hope to give points.
