Please help me find a joke that I have written or read wrong Chinese characters.

In ancient times, there was a rich man who didn't read much and spent money to buy a county magistrate. On his first day in office, he went to court to ask questions, and touts handed in the prisoner roster and brought the prisoners to class. The first prisoner's name was Ran Jiajun, and the magistrate looked at the words Ran Jiajun and was a little puzzled. How did he get a name called Zaiyue? (After the ancient traditional Chinese characters, he looks like a handsome man) But the first day I asked questions, I couldn't care so much, and I wanted to show my grandfather's prestige, so I patted him and said, "In the future." Ran Jiajun was a little puzzled. He always calls his name first in class. Why does the new county magistrate want me to stop today? I took a step back at the thought that it might be the new rules of the host. The county magistrate looks a little worried. I called your name, but you didn't say yes, but took a step back. Another mallet: "Further back". RanGuJun hurriedly took a step back. The county magistrate was really in a hurry, thinking about the first day of questioning and finding something awkward for me. Shouting: "Further back". Seeing that the master was really anxious, Ran Jiajun said with a sad face, "Master can't retreat any more, there is a wall behind him." The county magistrate said, "I call your name." Master, I don't want to call you anymore, but I want to call you Ran Jiajun. Hearing this, the county magistrate blushed. He struck the gavel again: "What a handsome pockmarked face."
