Who can help explain the meaning of dry wells and springs?

The well leads to the hole, and the water comes out of the well, so it has the image of a dry well and a spring. He who has a dry well and springs, if he has a well, has been dry for a long time and is only hit by heavy rain. Springs come out of the ground, and the water keeps flowing. Those who use this kind of divination have a sign of luck. As the saying goes, a dry well has been abandoned for many years, and once a spring water gushes out, it breeds envy of everything and luck turns to nature. In the past, Su once occupied this divination when he was 27 years old. Sure enough, he made a determined effort to study, became famous, and gave birth to Su Shi and Su Zhe, all of whom were ready to try. He wanted to use dry wells to generate springs for divination. "Poetry" said that "a dry well gives birth to a spring, and its reputation is greatly enhanced. Although it used to be complicated, it naturally developed backwards. The spirit of "end of the moon" is getting better and better, and the fortune is increasing day by day. Everything is easy to get in and out.
