由于四面环水的城市形制阻碍了赣州的进一步发展，知军洪迈开始在贡江上建造

As the city shape surrounded by water hindered the further development of Ganzhou, Zhijun Hongmai began to build a pontoon bridge on the Gongjiang River, which opened up the further expansion of Ganzhou City across the river. Due to the wide and turbulent flow of the Gongjiang River, it was difficult to build wooden or stone bridges due to the limitations of capital and technology at that time. Zhijun designed a pontoon bridge composed of hundreds of wooden boats, which is a special landscape heritage of the ancient city of Ganzhou. This makes Ganzhou develop from a city along the river to a city across the river. However, as the density of cities continues to increase, the problem of waterlogging has begun to appear again.

As the urban system surrounded by water hindered the further development of Luzhou, Zhijun Hongmei began to build a pontoon bridge on the Gongjiang River, opening the further expansion of Luzhou City to the other side of the river. Due to the rapid flow of wide water on the Gongjiang River, limited by the capital technology at that time, it was difficult to build wooden or stone bridges, Zhijun designed a pontoon bridge connected by 100 canoes, which is a special landscape heritage of the ancient city of Zhangzhou. Luzhou developed from a city lined with rivers to a city across the river. However, due to the increasing density of cities, the problem of waterlogging is beginning to appear again.

Because the city shape surrounded by water hindered the further development of Ganzhou, Zhijun Hongmai began to build a floating bridge on the Gongjiang River, which opened the further expansion of Ganzhou City to the other side of the river. Due to the wide surface of Gongjiang River and the rapid flow of water, it was difficult to build wooden or stone bridges due to the limitation of capital and technology at that time. Zhijun designed a floating bridge connected by 100 wooden boats, which is a special landscape heritage of Ganzhou ancient city. Ganzhou has developed from a city near the river to a city across the river. However, due to the increasing density of the city, the problem of waterlogging began to appear again.<br>
