"Where can a beautiful woman teach me how to play the flute?" Whose poem is it in? What is the whole poem about?

To Judge Han Chuo of Yangzhou

Du Mu

The green mountains are faint and the water is far away,

The grass in the south of the Yangtze River has not withered after autumn.

Twenty-Four Bridges on a moonlit night,

Where can a beautiful lady teach me how to play the flute?

On the moonlit night of Twenty-Four Bridges, where can the beauty teach me how to play the flute? The faint blue water and green mountains drift far away with the current. Did the vegetation at the end of the river wither for the flute music that sounded like water and ice? Looking back from ancient times, who used her cherry lips to faintly spit out the eternal Chinese sound. The Shuyu Liang Temple at the top of Huashan Mountain lamented the endless emotions of the daughter in the boudoir. The wonderful sound was quiet and disgusted with arrogance, and it was fluent. The low and euphemistic tune embodies Nongyu's peaceful and distant reverie and delicate and rich emotions. Quiet and elegant, with endless aftertaste. The clear blowing of the flute is the most touching thing. If there was no Xiao, how could Xiao Shi come by the dragon and finally stay with Nongyu for the rest of his life? If there is no flute, how can the pure and distant romantic imagination express the feeling of being far away from the world, otherworldly, living in seclusion in the mountains and forests, and living in peace and tranquility in the mountains and rivers? The tranquility and freedom in the mountains and forests is the contentment of Tao Qian picking chrysanthemums under the eastern fence and leisurely seeing the Nanshan Mountains; the romance and chivalry in the great mountains and rivers is the leisure of Du Mu's twenty-four bridges under the moonlit night, and the beauty who taught him how to play the flute; mediocrity The sighing up to the sky in the officialdom is Du Fu's endurance that makes me unhappy; the various worries in my daughter's boudoir are the gentleness of leaning on the wind and melting Chinese powder, sitting on the moon and complaining about Qin Xiao; the high integrity and integrity in the literary field since ancient times are the breakable jade The whiteness of the bamboo cannot be damaged, and the bamboo can be burned, but the pride of its joints cannot be destroyed! Even though it is not as loud and clear as the flute in expressing joy, and not as intense as the pipa or guzheng in expressing sorrow and fear, the implicit sound of the flute is best when it expresses pathos and generosity. It has the magnanimity and gentlemanly demeanor of a loyal elder. It is precisely this that always makes the sound of the flute linger in our ears for three days. The speed is slightly faster, and the waves are stacked, beaten, trembled, and given away, making people robbed by the gods. They dance like a crane, spinning higher and higher. Suddenly, they fall to the bottom and are inaudible at the bottom. The sadness and sadness of the sobs suddenly stop. What is left to us is endless elegance and elegance, relaxation of tense nerves, pursuit of emotional peace, sublimation of thinking and consciousness, and the most beautiful enjoyment. Playing the flute is called Xiaopin. The character of the flute is unmatched by anything else. It is quiet, inactive, ethereal, and ignores wine, sex, and wealth. It is scattered into mud and crushed into dust, but it has an integrity that is not stained by the world.

If the mind is restless and the mind is restless, even listening to a single sound is considered blasphemy. How can one be qualified to hold the flute and travel to the ends of the world?
