Is it cold to go to Yungang Grottoes during the Spring Festival?

In the north, it’s all about the solar terms. This year’s Spring Festival is seven or nine. As the saying goes: Seventy-nine rivers open and eighty-nine swallows come. It’s not cold anymore, but you still need to wear thicker clothes, such as sweaters.

It shouldn't be too cold during the Spring Festival, it's already seventy-nine, and the weather is good without snow.

I haven't been there in winter, it shouldn't be cold, the temperature here is not low

I went to Datong during the Spring Festival, just in time for the snow and cold, so I wore sweaters and down jackets, but the tour of Yungang Grottoes is basically not affected by the seasons. <br/>The picture below is the Yungang Grottoes in the snow.
