Preside over a joke performance

Hello, everyone, now the campus TV station begins to broadcast, and now the world-famous broadcaster of our school will host a channel audio-visual TV program for you.

According to my accurate observation in the window before the program, it is expected that the campus weather forecast today is as follows. Within half an hour, the weather forecast for all areas of colleges and universities in China is as follows:

In the boys' dormitory area, the weather is sunny and the temperature is 2-4 degrees different from this time yesterday. The wind force is 2-3. Students with sweaty feet can hang their shoes on the balcony without blowing them away.

In the girls' dormitory area, the weather is sunny and the temperature is 2-4 degrees different from this time yesterday. The wind is 2-3, and you can't dry stockings. Articles are carefully blown away by the wind, hurting pedestrians passing downstairs.

The staff dormitory area is sunny, and the temperature is 2-4 degrees different from this time yesterday. The wind force is 2-3, and the precautions are the same as those in male and female dormitory areas.

Playground:

Sunny, the temperature is 2-4 degrees different from this time yesterday. The wind is 2-3, please pay attention to prevent howling. Boys and girls who study together should pay more attention to the prevention of howling and sit under the big tree to avoid howling into a black wolf.
