Is Tianjin long in summer? About a few months.

I have been in Guangxi and now I live in Tianjin. I feel that the weather in Tianjin is more comfortable than that in the south. Summer in Tianjin is only hot at noon, and it is cool in the morning and evening, not as sultry as in the south. Winter in Tianjin is not too cold. There is heating in the room, and the average temperature in the room is above 16 degrees Celsius. Just wear a pair of woolen pants outside, and a down jacket is enough. I am a person who is afraid of the cold.
