Ask about the weather in Hangzhou and Shanghai during the Spring Festival ~ ~

I come from Hangzhou. It's sunny in Hangzhou these days, with a minimum of 4 degrees and a maximum of 15 degrees.

Generally wear a long T (you can take it off where there is air conditioning), plus a sweater and a thicker coat (cotton coat)

I'm not too afraid of the cold. I usually wear a long T and a thick coat.

Oh, I'm just going to Xiamen during the Spring Festival. I just learned about the weather there. Hangzhou is definitely colder than Xiamen. You should be prepared.
