Are elk afraid of cold? Can you live in the northeast?

Elk is afraid of cold and likes to live in warm and humid places, especially in the eastern part of the Yangtze River basin (only Beijing and Jiangsu breed a little more in the country); According to the data, the fossils of ancient milu deer only appear in Liaoning to the Yangtze River valley, so there should be milu deer living in the northeast of the southern region. As for whether I can live in the northeast now, I can't do experiments for the time being because it's too expensive.
