Will it be cold after beginning of spring in northern Fujian (Wuyishan)? When is it coldest in a year?

The coldest time in Wuyi Mountain in a year should be January, and the lowest time should be MINUS three to five degrees, but such days are rare.

As for beginning of spring, there will be fewer cold days. If I want to travel to Wuyishan, I think I can look at the weather forecast in advance and take the weather in Nanchang as a reference.
