Let's talk about how cold the Tanghe River is this winter.

The lowest temperature at night is around -5 degrees, but there are also some very cold situations. The lowest temperature reached-1 1 degree last winter. The maximum temperature during the day is generally 1 ~ 4 degrees, except for a few cases, the maximum temperature is above 0 degrees. But Henan is a big place and the temperature is different. I am talking about Zhengzhou.
