I plan to climb Huashan Mountain in Xi next night. What's the night temperature in Huashan now? Cold not cold? How thick clothes do I need to bring?

I just got back from Huashan. I wore a thin sweater, a light coat and a cowboy when I climbed the mountain, and a thick coat when I went to the top. I don't feel cold (I am a girl who wears a lot, and my boyfriend wears short sleeves and thin long sleeves, and wears a thin coat on the top of the mountain). It's not cold when climbing mountains, but cold when resting, especially at sunrise. We didn't rent a coat.
