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, spring changes a lot. After the Qingming Festival, there will be plum rain here. In the rainy season, it began to rain again, hehe. Basically, there will be thunderstorms and typhoon storms in summer and autumn, hehe. In contrast, it rains the least in winter, hehe.
