Is Shijiazhuang colder than Tangshan?

I grew up in Tangshan, and I went to school in Shijiazhuang on the first day of this year, catching up with the first winter in Shijiazhuang. Students in Shijiazhuang said that the winter in Shijiazhuang was not cold before, and the temperature was basically around 0 degrees. Last winter, the temperature in Tangshan was around-10 degrees. The climate has been abnormal in recent years. Today, the temperature in Shijiazhuang reached MINUS 7 degrees, and the temperature in Tangshan reached MINUS 12 degrees. So the weather in Shijiazhuang is still a little warmer than that in Tangshan.
