Jinan was not so big before. You can look at the moat, which is the river in Black Tiger Spring Park.
Jinan was once surrounded by that river, which was formed by spring water.
Finally, it all flows into Daming Lake.
Daming Lake at that time was at least two or three times bigger than it is now.
Jiefang Pavilion is the only remaining city wall (as if it had been rebuilt in situ).
There was no pollution at that time, and the whole city was full of springs.
Calculate, the area of Daming Lake can also account for less than half of Jinan City.
Daming Lake is also full of lotus flowers, and willows are everywhere by the river and spring.
What a refreshing feeling it is ~
So this poem is a description of the scenery of Jinan at that time.
