Where is Yanping Tianjin Lake today?

Yanping Lake is located at the confluence of Jianxi and Xixi at the source of Minjiang River. Yanping city is built on the central bank of the "confluence of two rivers". According to the Book of Jin? Zhang Huachuan: During the reign of Emperor Jinhui, Lei Huan was appointed as the county magistrate of Fengcheng, Jiangxi. When he was digging the foundation of the prison, he got a sword, one called Longquan and the other called Taiya. Lei Huan got this sword, gave it to Zhang Hua, the minister of the Jin Dynasty, and kept one for himself. Zhang Hua lost his sword after he was punished. After Lei Huan's death, Lei Zi worked in Huawei. On one occasion, Lei Hua took a sword from Jian Xi and sailed through Yanping Tianjin. Suddenly, the sword jumped out of its sheath and jumped into the water. When everyone reached the bottom of the water, they found that the double swords had become male and female Ssangyong snuggling together. The legend of "turning swords into dragons" came from this, so Nanping is also called "Jin Jian".
