I suggest you listen to the famous prose recitation, and Baidu will find it. I remember Wang Xuechun's mother had a version, which was very nice, but the name was forgotten, and then you just had to imitate it. You can find a CD-burning master outside to do it for you, just cancel the original sound. Generally, such stores will have relevant audio production software. All you have to do is ask for it and pay at last.
The best way for five people is for a man and a woman to recite, and the remaining three people should be harmony, which requires a manuscript. It's probably no problem to ask the teacher to help you correct it.
