Why does it always rain in Yiwu, Zhejiang?

In the south, there are many spring rains. It rains a lot during Qingming Festival, so it will still rain before Qingming Festival. It's basically rainy here, hehe, there are many changes in spring. After the Qingming Festival, there will be plum rain here. Speaking of rainy season, it rained again, hehe. Basically there will be thunderstorms and typhoon storms in summer and autumn, hehe. In contrast, it rains the least in winter, hehe.
