Winter in the North is always a little colder than in the South. If you wrap your coat tightly, the cold wind can still blow into your body through your sleeves. Snow seems to be a common substance, floating in the sky every day, and I get tired of seeing it too much. Therefore, after living in this city for three years, I am still not very accustomed to it. I cannot avoid catching colds and fevers in winter. But being sick means being sick, and work continues every day.
