Summarize the relationship between "China" and weather changes with short sentences (preferably proverbs)

It rains from big to small in Central China.

Rihua and Yuehua mostly appear at the edge of cumulus clouds, and the ultraviolet red ring is small to sunny days.

China Central is so big, it rains continuously, and it clears up after a storm. On the cloud screen opposite the sun, the colorful arc of Donghong rumbles, and the rain clouds of Xihong appear sooner or later. The sun shines on the red clouds, which turn red and the morning glow never dies.
