There are so many cicadas in the trees in Shanghai

There are so many cicadas in the trees in Shanghai. When people pass by under the trees, they might think it's raining. Their faces get wet and their mouths taste sweet. Looking up, they find that it's actually the cicadas urinating all at once.
I'm not making this up. If you search for information about cicadas in Shanghai, you'll find that they've overrun the place.
Experts say this year is a "cicada boom year", which is why so many cicadas have emerged.
Coincidentally, people in Shandong love to eat cicadas. This summer, there are even more cicada - catchers in Shandong than there are cicadas. They complain that there aren't enough cicadas in the trees and have even dug out all the cicada nymphs underground.
It's also a boom year, but why haven't all the cicada nymphs in Shandong come out?
People in Shanghai have come up with many ways to get rid of cicadas. It would be great if all these cicadas flew to Shandong. People in Shandong have a single - solution method: deep - fry them in a pan. They can even sell the surplus ones for money.
Some people have proposed a good idea: let people from Shandong come to Shanghai to catch cicadas. But how is that possible?
The average salary in Shanghai is higher than that in Shandong. Would it work if people in Shanghai shared some of their salaries with those in Shandong?
Moreover, some workers' pensions range from 10,000 to 20,000 yuan, while elderly farmers only receive a subsidy of 100 to 200 yuan. Would it be feasible to take some of the workers' pensions to supplement the farmers?
