I want to go to Yangzhou on 20 10 National Day. I want to know the weather and clothes there.

It should be cool in autumn. If you haven't met an autumn tiger in the past few years, you usually need a long-sleeved shirt. I suggest you visit China Meteorological Network one week before National Day. There are a lot of weather information and tourist indexes on it. I hope it helps you!

Welcome to the beautiful ancient city of Yangzhou!
