It's cold, how should I send a message to the leader?

Through inquiry and narration, it is said that there is no heating at home, it is a little cold, or it is still cold after all the air conditioners are turned on. I don't know what's going on, my family or myself caught a cold or something. Let's go on, how is your family? Did you turn on the air conditioner? Cold not cold? You should also pay more attention to keep warm. It's winter now, and the temperature difference between morning and evening is large. Don't catch a cold like my family or myself.

Hope to adopt!
