Compared with winter in the south, what's the winter like in Xi?

Hello, I didn't know you were from the south? My family is from Xi, and I am studying in Nanjing now. Take the Yangtze River Delta as an example. It's cold, humid and cold in winter here, and it feels windy. Because the Yangtze River Delta is not far from the sea, I always feel that the sky here is gloomy, and there are few cloudless days in Wan Li. . Xi 'an is located in the middle of China, north of Qinling Mountains, and the humidity in the south can't reach Xi 'an, so the humidity in Xi 'an is not as heavy as that in the south, in other words, it is not cold. But it was dry and cold. So it gives you the feeling that although the temperature in Xi 'an is slightly lower than that in the south. But it is not as cold as the south. Because Xi 'an lives inland, the sky in Xi 'an is often cloudless in Wan Li all day. Or even on a cloudy day all day. Xi 'an is basically not windy. There is heating in the room. But winter in Xi is very dry. In recent years, the winter temperature in Xi 'an is between 0 and MINUS 6 degrees.
