What should northerners bring when they travel to Nanjing and Yangzhou in mid-April? Pay special attention to what?

At present, the temperature in Yangzhou is in the range of 15-28 degrees. It is enough to cool down in the morning and evening, wear a thin coat and wear a T-shirt around noon. Yangzhou is located in a place where there is not much rain. Don't worry about the continuous rain. It rained these two days, and it turned cloudy and sunny behind. Actually, there's nothing to pay attention to. I suggest you ask Baidu about Yangzhou tourism. It will answer many questions about tourism every day.
