How different is the weather and food in Chongqing from that in Zhejiang?

There should be little difference between the weather in Chongqing and Zhejiang now. It is enough for you to go to Chongqing to prepare some long sleeves now, but you will definitely add clothes slowly after a while. As for food, because it is not too spicy, there are also light meals at school. If you don't eat anything in the hot pot at ordinary times, I believe the problem should not be big. I said what I want to say is that after you graduate from Chongqing, I believe you will like Chongqing's "spicy" food, especially hot pot.
