Budai, most known as "Fat Buddha" or "Laughing Buddha" was supposedly a Buddhist Zen monk who lived in China over a thousand years ago.

One legend tells a story illustrating the claim that Budai wanted people to stay positive and joyful. When the beloved monk died, many cried.  A huge crowd gathered around to take a last farewell with tears running down their checks. The fire was lit at the cremation ceremony. Then, to the surprise of most mourners present, there was a huge blast of fireworks.    

Before he died, Budai had secretly asked that firecrackers were hidden under his robe. That did that trick. All who were present at the cremation found themselves smiling.
