The weather forecast says there will be heavy rain tomorrow.

The city is a very small town, so there is no weather forecast station here. People go out with or without umbrellas, 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.

As a result, 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 Wan Li was clear.

Then, the old lady predicted, "It will be sunny tomorrow.

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 should get together and find a way. "Ladies and gentlemen, a duck named Mao said," I tell you, let's listen to the weather forecast backwards, shall we? ""No way out, try it! "So, when the old lady predicts rain, everyone will go out happily. If it doesn't rain, everyone will take an umbrella. In this way, it was peaceful for a long time, and everyone praised the clever duck.

Later, the old lady retired and the new director was a young man. He predicted: "It will thunder tomorrow, please make earplugs." But people don't take it seriously. As a result, thunder deafened more than 200 people's ears, and the hospital was suddenly overcrowded. The whole town was very angry and took to the streets to March and petition-condemning 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.
