What to wear to Putuo Mountain? The weather in early April.

I came to Putuo Mountain in May. The weather was good and the temperature was gradually rising. The average temperature during the day is about 2 1 degree, so I can wear a suit or casual clothes. It is recommended to choose sports shoes, which are convenient and good, and will not make your feet feel tired. The temperature drops at night, but the temperature difference is not very big, and the lowest temperature is about 16 degrees. After all, it will be cold in the mountains, so it is very necessary to put on a coat. Keeping away from colds is the most correct direction.
