Can northerners adapt to the winter in Yiwu?

Northerners in Yiwu can't adapt to winter. It's not as cold outside as in the north, but there is no heating indoors, and the humidity is very high, so it feels particularly cold. The temperature is not much higher than outside, and many northerners are not used to it. Yiwu has a livable climate. Yiwu is located in the subtropical East Asian monsoon climate zone, with four distinct seasons, mild temperature, abundant rain and sunshine, and obvious basin climate characteristics.
