Do I need to bring cotton-padded clothes or something like that when going to Huashan now?

You must bring some. The temperature in the mountains will be 5-10 degrees lower than the temperature in the city (you can refer to the weather forecast in Huayin County). There will be light snow and snow in many places on the mountains. It is recommended that you bring some. Wear light but warm clothes, and bring two sets of underwear. Because you have been moving up the mountain, you won’t feel cold, and you may sweat more. But when you return to the resting place after climbing the mountain, it will be very cold. If you don’t change your underwear, you can imagine what it will be like. Such a situation, haha. In addition, things on the mountain are relatively expensive, as are any scenic spots. For example, a bucket of instant noodles will cost 10 yuan. You can use this ratio to calculate.
