I agree that the flipside of the humidity in places like Zhejiang, also equates to miserable, cold, damp winters. How I longed for real snow like in north china and central heating during those miserable, oppressive winters.Sub-tropical is being a bit optimistic in how they categorize Zhejiang, it does not have banana or eucalyptus trees like guangdong province has, and even there it gets cold in winter!!!!!
