Is it cold at 12-18 degrees during Qingming Festival in Xiamen this year? What kind of clothes should I wear?

The weather in Xiamen changes very briefly. For example, it rains in the morning and usually becomes sunny in the afternoon, but it usually rains during Qingming Festival. As for whether it's cold or not, we usually wear the thinnest autumn clothes. If it's hot, we usually feel too hot if we wear short sleeves. So I suggest you wear short sleeves underneath and a thin coat for autumn. You can wear it when it’s cold and take it off when it’s hot. We don’t know what the weather will be like this year, so it’s hard to predict. The most important thing is that you don’t catch a cold. Pay more attention to weather changes.
