The weather forecast says there will be a rainstorm tomorrow.

City A is a very small town, so there is no weather forecast station here. People take umbrellas or not when they go out, and how many clothes they wear depends on their own feelings. If someone gets caught in the rain or something, they have to admit that they are unlucky.

thus, a meteorological observatory came into being. The director is an old lady. Every day, the old lady broadcasts the weather forecast from the loudspeaker: "There will be heavy rain tomorrow, please bring rain gear."

However, the next day it was clear in Wan Li.

Then, the old lady predicted, "Tomorrow will be a sunny day.

So everyone took out the quilts to dry, but it rained cats and dogs the next day. In the evening, everyone held the wet quilt and shivered all night.

this kind of thing happens every day, so we have to get together and find a way. "Ladies and gentlemen, a duck named Mao said," I'll tell you what, let's listen to the forecast backwards, shall we? " "No way out, try it!" Therefore, when the old lady predicts rain, everyone will go out happily, and when it predicts no rain, everyone will take an umbrella. In this way, it was peaceful for a long time, and everyone praised the smart duck.

Later, the old lady retired and the new director was a young man. He predicted: "There will be thunder tomorrow, please make earplugs." But people didn't take it seriously. As a result, the thunder deafened more than 2 people's ears, and the hospital was suddenly overcrowded. The whole town was angry and took to the streets to March and petition-denouncing the hateful behavior of the new weatherman. So the mayor had to invite the old weatherman-the old lady back-to continue broadcasting the "contrast" weather forecast.

Everything is back to normal, because people are used to listening to the old lady's weather forecast backwards.
