Riding on the dusty princess and laughing, no one knows where litchi comes from.

"Riding a dust princess laughs, no one knows it is litchi". The "litchi" in "Riding a dust princess laughs" comes from Lingnan. From Du Mu's poem "Crossing the Qing Palace" in Tang Dynasty. "Chang' an looks back at the embroidered pile, and the top of the mountain opens a thousand times. Riding the world of mortals and laughing, no one knew it was litchi. "Looking back at Chang 'an, Mount Li looks like a pile of splendid scenery, and thousands of doors of Huaqing Palace are opened in turn at the top of the mountain. As soon as I rode, the smoke billowed and the princess smiled. No one knows that the south has sent litchi fresh fruit.

This poem lashed out at the extravagant life of Xuanzong and Yang Guifei through the typical event of sending litchi, and its artistic effect was subtle, exquisite and well-known.

The first sentence describes the scenery of Mount Li where Huaqing Palace is located. The poet writes from the perspective of "looking back" in Chang 'an, just like a film photographer. First, he shows a broad and far-reaching panorama of Mount Li in front of the audience: lush trees, lush flowers and plants, palaces and castles stand among them, just like a beautiful group. "Embroidered Pile" not only refers to the East Embroidered Ridge and the West Embroidered Ridge on both sides of Mount Li, but also describes the beauty of Mount Li.
