I will visit Changsha in March last week what kind clothes are required, especially abt woolens

From today (March 25th) on, it rains there till March 28th and on March 30th. On March 29th, it shall be a cloudy day! Also as the temperature shall range from 15℃ to 24℃, I suggest you prepare relatively thick long-sleeved shirt, jacket and jeans as well as an umbrella, no woolens needed. Hope this is not too late!
