What is this calligraphy written in the picture? Is it Ping lusa San or Ping Shuang Sha San or other words? What do you mean? What is the source?

The content of this calligraphy work is:

Prosperity is 3000 yuan. Looking down, it is foggy. If you want to drive, it's sunny.

In order to avoid repetition, the writing of two of them has been changed.

It is a language that people lament the impermanence of life and don't care much. It has no source.
