What was the weather like in Changsha on September 20th? What clothes did you wear?

If you take the normal route and refer to the weather in previous years, it will be colder at the end of September. This year is special, the overall temperature is low, and it is very cold in August now, so it may be a little colder in September this year than in previous years. It should be a coat. But who knows, the weather in Changsha is random.

To be on the safe side, a pair of jeans+long sleeves+thin coat. I am sure it is.
