Historical evolution

Before the Ming Dynasty, from the East head of the current South Sophora tree to the north, through the East Street and Jinger road of Zhongda Sophora tree, to the west head of the North Sophora tree, there was a earth stone hill, high in the South and low in the north, winding and undulating, which looked like a long dragon. Trees were planted on the hill to resist the wind and sand. The Huaishu area in the south is well populated, so it is called panlongzhuang.

Before the first year of Wanli in the Ming Dynasty (1573), because there were many ancient locust trees in the village, it was renamed Da Huai Shu Village.

Before the 36th year of Qianlong in Qing Dynasty (1771), it was divided into three big pagoda tree villages: South, North and middle. In 1904, after Jinan opened a commercial port, the three big huaishuzhuang in the south, North and middle gradually became urban residential areas.

In the 36th year of the Republic of China (1947), the name of Huaishu village in South, North and Zhongda was cancelled, and its central streets were changed to NANDA Huaishu street, Beida Huaishu street and Zhongda Huaishu Street respectively. After liberation, the streets and alleys of South Huaishu street, North Huaishu street, Zhongda Huaishu street, huaicun street and Huaiyin street were successively derived.

In 1955, according to the State Council's instruction that "city districts should be changed to place names", the Sixth District with more streets and lanes named after Huaishu was changed to Huaiyin District.

In May 1961, the regionalization of 1956 was restored.

In August 1966, Huaiyin District was renamed Dongfeng district.

In July 1973, Dongfeng district was renamed Huaiyin District.
