The Legend of Jing Hua Yuan

During the reign of the Empress Wu Zetian, the Empress orders that all the flowers in her garden bloom all together. The Flower fairies, fearing her power, follow her orders but they are soon punished by the Jade Emperor for disrupting the course of nature: they will reincarnate in the human world and only when their penance is complete, will be allowed to go back to Heaven.
