Introduction to the Jade Pavilion: The Jade Flower is rare in the world. In the Tang Dynasty, only the Emperor's Royal Garden and the Hanlin Academy were allowed to plant it. When it blooms, it looks like a jade tree. Therefore, there are myths and legends such as fairies coming down to earth to enjoy it. When Li Deyu, the prime minister of the Tang Dynasty, was the governor of Runzhou, he often came to Zhaoyin Temple to drink under the Jade Flowers, and built the Jade Pavilion specifically for viewing the flowers.
