What's the climate like in Xiangtan for one year? How cold is winter and how hot is summer? How long does winter and summer last respectively? Try to be as detailed as possible.

As a native of Xiangtan, I have to tell you that the climate here in Xiangtan is very unreliable ~ ~ It has been hot since May in the solar calendar! It can reach 40 degrees when it is hot. The appearance of eleven almost began to get cold, and the coldest can be MINUS 2 to 3 degrees. What I hate most is that it usually rains, which is wet and cold! Anyway, one thing is that the weather is changeable. You still wear short sleeves today, maybe you will wear three tomorrow ~ ~ ~ I don't have the impression of spring and autumn, haha
