What's the weather like in Luoyang in October? What was the temperature in previous years?

/kloc-The temperature is still relatively hot in early October, so I can wear whatever I say, but during or at the end of the National Day holiday, according to my experience of more than 20 years, the temperature will generally drop significantly, and the sweater will be changed. By the end of 10, it is basically cold in the morning and evening, about a few degrees, and girls will change long-sleeved sweaters. Because of the large temperature difference, it will still be very hot at noon, and it will be about 20 degrees when the weather is good.
