The river was a vast unbroken stretch back in the Tang Dynasty. However, during the Chenghua period of the Ming Dynasty, a giant sandbank was left in the middle of the river after a flood.
At the time, the counties of Min, Houguan, and Huaian all tried to claim the sandbank as theirs, resulting in a dispute. Hence, the provincial government brought in a verdict that the sandbank would be co-administered by all three counties, and was given the alternative name "Three-county Islet", which was the River-center Park nowadays.
When time came to the modern age, the surface of the river remained quite wide at Longtan Corner, but the government dared not let its guard down, and had made ample preparation work beforehand for this operation.
