Every Sunday, in the park pavilion next to the community, there is always a group of elderly people who love Peking Opera get together to play and sing and perform a different style of pear orchard. In the crowd of accompaniment, a thin old man with silver hair but good spirits caught my eye. He is a Jinghu, I saw him holding the rod in his left hand, his fingers pressing, kneading, beating, and slipping on the strings, up and down, flexible and abnormal, pulling the bow with his right hand, one long bow, one short bow, pushing, trembling, shaking, and all kinds of skills are used perfectly. A string of notes poured out under his hands, the listener was drunk, and the old man who played the violin himself was drunk, he followed the melody, closed his eyes slightly, shook his head, shook his hair, immersed in it, as if no one was around, his arm pulled the bow between opening and closing, and his movements were like flowing water, extremely chic. What's even more rare is that no matter which aunt wants to sing a piece of "Suolin Bag" or "Su Sanqi Solution", or which uncle wants to sing a piece of "Quanmei Case" or "Dingjun Mountain", he can always switch freely between the strings, the accompaniment never drops the chain, and a Jinghu is simply divine in his hands, no matter how I look at him, he is like a hidden master with a peerless education. When I have nothing to do, I always like to listen to the old people singing and watch this old man pull Jinghu. After a long time, I got acquainted with a few aunts who sang Peking Opera, and chatted with them and learned that the old man of Lajinghu was not the worldly master I imagined, he was just an ordinary retired music teacher, who played the huqin well, and his wife married him when he was young. My wife suffered from Alzheimer's disease two years ago, and I can't remember many things, but when I hear the old man Lajinghu, I will be calm and quiet. The old man took good care of his wife and played the piano for his wife every day, he said that as long as the sound of the piano can still evoke the remaining memories of his wife, as long as his wife is still willing to listen to him play the piano, he will continue to play it. On weekends, the children come back to help take care of their wives, and the elderly have time to go to the park to gather with a group of friends who like Peking Opera on weekdays to accompany them. The small pavilion is a small stage in a place, with gongs and drums opening, drums ringing in unison, and the old people singing in turn, which is a unique scenery in the park on Sunday. After the old people had their fun, they went back to their homes, and the old people in Lajinghu also packed up their belongings and drifted away. After the noise, I don't know what kind of sadness the old man's heart will have when he thinks of his lover who has been with him for a lifetime, and will forget everything in the end. But I think that in the sound of his piano, my wife forgets the three thousand things of the world, and it is not another kind of consummation.
