Wait online the day after tomorrow and go to Huangshan on March 26th. Is it cold now? The lowest temperature in weather forecast is-1 degree. Is it necessary to bring a down jacket?

If you don't go to Huangshan scenic area, come to Huangshan, and you don't need to bring a down jacket. I just wear a thicker coat here every day. The temperature here was extremely high yesterday, and the sun was shining outside. But if you are going to Huangshan Scenic Area, you must bring it. The top of the mountain is very cold at night. Wearing cotton-padded clothes, I am in Huangshan, and it is sunny today.
