Where is the origin of "Jing Hong" in "Once Jing Hong took a photo"? What is the original sentence?

Shen Garden Author: Lu You painted a corner to mourn the city in the sunset, and Shen Garden is not a revived pool platform; Under the sad bridge, the spring waves are green, which used to be a stunning photo. The Original Poem is the most widely circulated poem in the past 50 years. Lu You died of depression in Tangwan. "The spring waves under the sad bridge are green, which was once a stunning photo" is the place where the author tries his best to find memories. He saw "the spring waves under the bridge are green", and as always, he felt as if he had met an old friend. It's just that this scene caused not joy, but "sad" memories. "This is an amazing photo." Forty-four years ago, Tang Wan, like the fairy described in Cao Zhi's Luo Shen Fu, floated on the spring waves. She was so gentle and sad in gracefu, but now everything is irreversible, and that amazing photo is gone forever. However, as long as this heart is immortal, this "shadow" will remain in my heart forever. Shenyuan is the place where Lu You and Tang Wan met and fell in love. This is not only their Garden of Eden, but also the destination of their love. Lu You's mother didn't like Tang Wan very much, so she forced them to break up. Lu You was forced by her mother's orders to leave reluctantly. Tang Wan remarried, and Lu You also remarried Wang. 10 years later, they met in shenyuan, and Tang Wan treated each other with wine. Lu You was deeply moved by his feelings, so he wrote the word "Feng Feng" on the garden wall, expressing the pain and sadness that he could not bear to be separated, as well as the bitter thoughts after separation. Tang Wan read it, deeply grieved, and soon died of depression. As a result, Shenyuan became the land of lovesickness for Lu You's whole life. After 40 years of "broken dreams and fragrant sales", Lu You was 75 years old and came to Shenyuan to relive the past. Tang Wan's voice and face are full of smiles: "The spring waves under the sad bridge are green, which used to be a stunning photo." Especially when he was 8 1 year old, he came to Shenyuan to share his physical injury here, and he was deeply saddened: "It is spring in the small town south of the city, but plum blossoms are nowhere to be found." A dying white-haired old man shouted "I only see plum blossoms but no one" to a tree full of plum blossoms, sobbing, what a spoony man! He obviously wants to go to another world with this unforgettable love and acacia to pursue the Iraqis who enjoyed plum blossoms under the tree that year. This is the true meaning of Sauvignon Blanc-Acacia is as long as life! After all, there is nothing in the world but lovesickness. I don't want to miss you, so I won't miss you. Think about it carefully and want to miss each other. However, perhaps transportation and communication are too developed, so modern people are less homesick, less expected and moved. Someone loves you all your life, and someone tells you to love you all your life. You are the happiest person in the world.
