What is what we hope, flying in heaven, two birds growing together on the earth with one wing, two branches of a tree. Mean?

It's the third and fourth sentence from the bottom of the everlasting regret. Emperor Xuanzong of the Tang Dynasty and Yang Guifei swore in the Palace of Eternal Life that they would be two birds in Qi Fei's wings in the sky and connected branches on the ground, and they would be loving couples forever. Poetry is beautifully written and often quoted by later generations to show loyalty to love.

The connecting branches and connecting branches of a lovebird refer to two trees connected together. Love birds, a legendary bird, is used as a metaphor for loving couples in classical poetry. Legend has it that in old China, King Kang of Song married Han Ping, an official, and imprisoned Han Ping. Han committed suicide and his wife's clothes were rotten. When she went on stage to play with King Kang, she threw herself under the stage and everyone pulled his clothes. As a result, she fell to her death, leaving a suicide note saying that Han Ping was buried together, but Kang Wang buried them in two places. Soon, a catalpa tree was born on each of the two graves, and it grew very thick in ten days. The roots and branches of two trees are intertwined, and there is a pair of mandarin ducks on the tree, groaning at each other. Bai Juyi's Song of Eternal Sorrow: "On the seventh day of July, in the Palace of Eternal Life, we secretly told each other in the quiet midnight world. We hope to fly in heaven, two birds grow together on the earth with the same wing, two branches of a tree ... "

The Everlasting Regret

Author: Bai Juyi

The emperor of China, eager to shake the beauty of an empire, has been in office for many years, searching and never finding it. Until a child of the Yang family grew up in the inner room, almost before she grew up, and no one knew her.

However, due to the gift of heaven and no concealment, it was finally elected royal one day. If she just turned her head and smiled, there were a hundred spells, and the powder and paint of six palaces disappeared without a trace.

It was early spring. They let her bathe in a pure pool to warm and smooth her creamy skin. Because she was tired, a maid lifted her up, when the emperor noticed her for the first time and chose her as his bride.

On the night of spring, the warm hibiscus curtains covered her fluttering hair, petals on her cheeks and golden ripples on her head. But the night in spring is short and the sun rises too fast. Since then, the emperor has given up his early hearing.
