The general content of the Minghu Residence textbook is as follows:

At 12:30, a man came out from behind the curtain. He was wearing a blue robe. His face was long and full of bumps. It looked like the skin of a dried orange. He was very ugly, but he smelled calm. He walked out of the stage without saying a word and sat down on a chair on the left side of the table. He slowly took out the three-stringed instrument, casually played a chord, and played one or two minor tunes. He didn't pay much attention to it. Later, she played a major tune, but she didn't know what brand it was called. However, later on, he used the tremolo finger. That cadence was so moving that it was as if there were dozens of strings and hundreds of fingers playing there. At this moment, the cheers from the audience were endless, but they could not suppress the music. After playing the song, they stopped and someone brought tea over. After a few minutes, a girl of about sixteen or seventeen came out from behind the curtain. She had a long oval face and a bun. She wore a pair of silver earrings, a blue jacket, and a pair of blue trousers, all of which were inlaid with black cloth. Although it was coarse cloth, it was very clean. He sat down on the chair on the right behind the table. The person who played the string took the string and bounced it up. The girl stood up, took the pear flower slip in her left hand, held it between her fingers, and knocked it with a tinkling sound, corresponding to the sound of the string. Her right hand held the drum and hammer, listening attentively to the rhythm of the string. Suddenly there was a sound of Jie drum, and the voice suddenly sounded. The words were clear and melodious, and the sound was like a new oriole coming out of the valley and a young swallow returning to its nest. Each sentence was seven words, and each paragraph was dozens of sentences, some slow and some urgent, sometimes high and sometimes low. The place where the tune changed was ever-changing. I felt that all the tones of the songs were better than this one, and I thought it was the best. There were two people sitting next to him. One of them asked the man in a low voice,"This must be Bai Niu, right?" "No," said one of them. This person was called Hei Niu, Bai Niu's sister. His tune was taught by Bai Niu, if compared to Bai Niu, he didn't know how far away he was! His benefits could be said, but Bai Niu's benefits could not be said. His benefits could be learned, but Bai Niu's benefits could not be learned. Think about it, in these past few years, who wouldn't learn from them? Even the girls in the brothels all learned it, but at most, there were one or two sentences that reached the level of black girls. No one has ever been able to compare to him in terms of benefits to Ruo Bai Niu." As she said that, Hei Niu had already finished singing and went to the back. At this moment, the people in the garden were chatting and joking. The people selling melon seeds, peanuts, hawthorn, and walnuts shouted loudly, and the whole garden was filled with people's voices. Just as it was bustling with noise and excitement, another girl came out from the backstage. She was about eighteen or nineteen years old, and her clothes were no different from the previous one. She had an oval face and a fair complexion. Her appearance was above average, but she was beautiful but not charming. She was clear but not cold. She came out with her head half lowered and stood behind half the table. She clinked the pear blossoms a few times. It was really strange. It was just two pieces of hard iron, but in his hands, they had five tones and twelve temperament. He lightly tapped the drum twice before raising his head to look below the stage. Her eyes were like autumn water, cold stars, pearls, and two balls of black mercury in the white mercury. Looking around, even the person sitting in the far corner of the wall thought that Wang Xiaoyu had seen me, let alone those sitting close to me. With just one glance, the entire garden was silent, much quieter than when the emperor came out. Even a pin drop on the ground could be heard!
