I never quite believe this kind of talk, and consider it exaggerated.

In the past, I heard people say:

"Formerly, it was often cloudy and drizzly for days on end in the south of the juncture of Sichuan, Shaanxi and Hubei, with very few fine days in between. When the sun shone occasionally, the dogs would bark consistently without stop."

Six or seven years ago, I came to the south. In the winter of the following year, there was a heavy snow rarely seen before. It crossed the Naming Mountain and covered several prefectures in the southern part of Yue (Guangdong Province). Consequently, the dogs in these prefectures were all panic-stricken. They barked wildly and ran about in confusion for several days in succession. It wasn't until the weather had cleared and the snow melted that they became quiet.

Only by then did I believe that it was likely that the dogs in Shu (Sichuan Province) barked at the sun.

Of course there is nothing wrong with sunrise or snowing. In fact, the dogs just consider these phenomena strange out of ignorance!
