The weather in Changchun for one year

I come from Changchun, which is located in the campus of Jida University ... How can I say that the weather in Changchun is normal? It's MINUS 10 degrees in winter. I wonder how this classmate is physically fit. I will graduate from college soon, and my physique is good, but I still have to wear down jackets in winter and trench coats in autumn, so you will start school. The first semester is autumn and winter. It is recommended to bring thermal underwear with some sweaters or cashmere T-shirts in the middle. It is stipulated to wear down jacket or cotton-padded jacket in winter, but it is not excluded that there will be warm winter. In recent years, it has been warm in winter and naturally hot in summer. The recent temperature is around 25 degrees, and it is more when going up. There was a lot of precipitation a few days ago. Jida is also a good school in the country! The pride of Northeast China ~ If you don't know anything, you can continue to ask me ~! I will try my best to give the answer ~ ~
