Longsha, also known as Longsha Port, is located on the bank of Ganjiang River about three miles northwest of Nanchang Old Town. Now the sand nest is by the river, and the river bank is a sparkling white beach. Li Daoyuan's Notes on Water Classics said: "Sweet water is in the north and sand is in the west. The sand is very white, and the old custom has started on September 9. " The musical history of scholars in the Song Dynasty, The Jade Ring in Taiping, also records that in the past, "in the Qili area in the northern part of the mainland, rivers and sands run into hundreds of rivers, and people live around and see dragons". Longsha, since the Han and Jin Dynasties, is a good place to make friends.
Longsha, the highest place outside Deshengmen, the gate of the ancient city of Nanchang, is a place where old customs are valued and promoted, especially in the Tang Dynasty. Today, the area along the river in Longsha has become a swimming pool. Every summer, there are many men and women swimming, just like dragons swimming in the water. When the sun sets and the sunset clouds are all over the sky, the reflection in the water is particularly touching.
