1998年春, 郑州大学历史与考古系等单位对长垣宜丘遗址进行了考古发掘, 出土了一批龙山、先商和晚商等时期的文化遗存, 初步建立起当地考古学文化发展序列。尤其先商文化遗存的发现, 为研究漳河型先商文化和鹿台岗遗址先商文化之间的关系提供了重要资料。 In the spring of 1998, units such as the Department of History and Archeology of Zhengzhou University carried out archaeological excavations on the site of Yiqiu, Changyuan, and unearthed a number of cultural relics such as the Yongsan, the Shang and Late Shang periods and initially established the sequence of local archaeological culture. In particular, the discovery of pre-commercial cultural relics provides important information for studying the relationship between the pre-commercial culture of Zhanghe River and the pre-commercial culture of Luzigang Site.
