Chu people miss their homeland and named the new capital according to the theory of "the landscape is yin and yang, and the north water is yang", which is the theoretical basis of Dan Xi's theory. According to the custom that place names migrated with people in Chinese and foreign history, the name of "Jingshan" in Henan was also crossed by Chu people and transplanted to the southwest of Hanshui about 80 miles northwest of Nanzhang, Hubei, which is the geographical basis of Dan Xi's theory.
Due to the advancement of the Middle Route of South-to-North Water Transfer Project, ancient sites were rescued and excavated in the flooded area of Danjiangkou Reservoir. Yin Zigeng's tomb of Chu State (son of Chu Zhuangwang) unearthed in Xichuan, Henan Province, and a large number of tombs of Chu nobles around it have been discovered. In the Chu Wuwang period, the capital of Chu moved from Danyang to Yong (near Zigui County, Hubei Province).

According to Gao Chongwen, according to records, when Chu Zixiong was in office, he was named Teacher Wen. When he arrived in Zhou Chengwang, in order to reward the achievements of Zi Chu and Xiong Yi, the monarch of Chu awarded "Zi Chu as Danyang". Although these are documented, the exact location of "Danyang" is still unclear, and it is necessary to find the cultural relics unearthed from Chu in the Western Zhou Dynasty to confirm this statement.
"From the unearthed cultural relics, we speculate that there should be Chu nobles living here in the middle and late Western Zhou Dynasty, which fills the gap in clarifying Chu culture in the Western Zhou Dynasty and will have a far-reaching impact on the future study of Chu culture." Gao Chongwen said.
