According to historical records and expert research, ancient Jiang Guo was located in Zhengyang, and its territory was in the Huaihe River Basin. Its capital site is now Dalin Xiangtudian Village, which is 2 kilometers long from east to west and 1.2 kilometers wide from north to south. There are fragments of pottery used in daily life in Shang and Zhou Dynasties in the ruins of the ancient city. In 623 BC, Jiang Guo was destroyed by the State of Chu, and Jiang Guo's descendants fled and lived in different places, taking the country as their surname, hence the name Jiang. In recent years, in the activities of seeking roots and recognizing ancestors, some Chiang clan relatives at home and abroad have come in droves. Among them, the "Nanyang Jiangjiahui" in Xinjiapo has always kept in touch with the "Jiangjiahui" in our county, and donated money to build Yanhuai Primary School and Jiangs Ancestral Hall in Dalin Township.

There is a high platform in the northwest of the site, which is 8 meters high and covers an area of 2,000 square meters. It is the site of the Gujiang Pavilion. Jiangting still existed in the Western Han Dynasty. "The Fifteen Biographies of Liu Biao, Yuan Shu and Lu Bu in the Later Han Dynasty" contains: If you can't pass the art pass, you can't go back.

Notes on Water Classics: Huaishui is also in the south of Anyang County in East longitude, and Jiangguo is also there. Today there is Jiangting. In the Spring and Autumn Period, Wen Gong spent four years, and Chu destroyed the river.

In the ancient city of Jiangguo, there used to be legendary sites such as two cypresses, three bridges, two levels of seven mountains and two levels of twelve lotus ponds and moon bends, Phoenix Terrace, Jiangci, Jiangting, Woniudui and Cannongji. Now it's just a beautiful legend, adding some mystery to ancient Jiang Guo.
