1. Sanya
Situated on the southern tip of Hainan Province, Sanya is the southernmost city on the island. Featuring blue sky, beautiful beaches and clear water, Sanya is perhaps the most famous coastal city in China. The climate is hot in summer but warm in the three other seasons. When other cities are shivering in this month, a stroll along the coastline and breathing the fresh air will provide you with a warm, comfortable holiday.
