On September 18, the topic of playing on the court was that the flowers fluttered uncontrollably, the jade heart was bright and never moved. What animals are described?

Creatures with flowers and jade hearts. This sentence comes from the farewell sentence of the Tang Dynasty poet Bai Juyi: "The vast grass crosses the plain and comes and goes with the four seasons. Wildfire can't burn it out, but the spring breeze can revive it. Weeds and wild flowers are all over the ancient road, and the end of the grass in the sun is your journey. I once again sent my bosom friend, and the thick grass represented my deep affection. The flowers fluttered uncontrollably, and the jade heart was bright and unshakable. " As can be seen from the poem, what is described here is a creature with flowers and jade heart.
