Is it cold in Tomb-Sweeping Day 12- 18 degrees this year? What should I wear?

The weather in Xiamen is very short. For example, it rains in the morning and it is usually sunny in the afternoon, but it usually rains in Tomb-Sweeping Day. As for whether it is cold or not, we usually wear the thinnest autumn clothes. If the weather is hot, we usually feel very hot in short sleeves. So I suggest you wear short sleeves inside and a thin coat in autumn, which can be worn cold and taken off hot. I don't know what the weather will change this year, so it's hard to decide. The most important thing is that you don't catch a cold. Pay more attention to the change of weather.
