What is temparature in china during march and what type of clothe required?

Well, the average temperature of the northern cities is abour 8-10C and that of the southern cities is about 18-20C.

If you are going to certain northern cities like Beijing, I suggest you take along an overcoat, light sweater and jeans. While if for southern cities like Guangzhou and Shenzhen, you can take along long-sleeved shirt and coat. Sometimes, simple rainy gear or an umbrella is also necessary.
