What was the weather like in Beijing at the end of 10?

Cold air has come recently, so it's a little cold these two days. After a week, you have enough clothes, thin sweaters and coats. But I feel I have to wear long pants, otherwise my legs will freeze, and then someone will wear a small cotton-padded jacket. As you are from the south, you'd better take a thick coat. After all, it's the north, and the cool breeze alone is enough for you.
