Is Xinxiang cold in winter? What is the temperature? How many clothes should I wear?

Please prepare the following clothes in winter in Henan:

Coat: autumn clothes, sweaters, coats (or autumn clothes, thermal underwear, leather clothes)

Base coat: autumn trousers, woolen trousers and a pair of trousers (or autumn trousers, warm trousers and a pair of trousers).

You don't usually need to wear a hat. When it is below zero 10 degrees (this kind of weather is almost rare, and it is usually 5 ~ 6 degrees in the coldest time), you can wear down jackets. I wish you a wonderful and warm winter in our Henan province.
