There is an ancient Chinese saying, "Growth begins with the advent of spring thunderstorms. In China, during the spring time there are often thunderstorms where people hear loud thunder but there is no rain. It is hence referred to as "spring thunder." During this seasonal period, the temperature starts to rise and the frequency of rain increases in China. In the great outdoors of southern China the peach trees and plum trees blossom pink, red and white, and birds sit poised on tree limbs.
