In the Southern and Northern Dynasties(420-589), in the reign1 of king Wu of Liang, there was a monk2 called Master Yun Guang who was a very accomplished3（有技巧的） preacher. Once he explained the sutra（佛經(jīng)，箴言） so proformdly and subtly that the God of Flowers was moved and sent divine（神圣的） flowers down to earth. Soon the land was covered with flowers.

　　This idiom was later used metaphorically4 to describe talking in a vivid and eloquent5 way(mostly in an exaggerated and impartical manner).
