The guide explained the slogan.

I personally think this sentence is the most appropriate:

Lotus flowers on four sides and willow trees on three sides, a city with mountains and half a city with lakes.

The following are the slogans of some special scenic spots in Jinan:

Daming Lake is very big. There are lotus flowers in Daming Lake, and there are toads on the lotus flowers.

Qianfo Mountain is in complete darkness. Sharp at the top and thick at the bottom. One day, it was upside down, with a thick tip.

Baotu spring, spring sudden, three pipes as thick, glug.
