Yellow toad fortune telling

"Huang" is about a man. When his wife was raining, his leg was hurt, so Huang took an umbrella and everyone else laughed at him. As a result, he didn't get wet, but everyone else got wet. So everyone thinks that Huang can tell fortune. Someone asked him to calculate where the bracelet was, and he was blindfolded by mistake, so someone asked him to enter the palace to calculate his pearls, which happened to let him hear the report's conversation, so he did it. The emperor asked him to calculate what he had in his hand. He said that this early morning, the emperor said, "Yes, it's a big jujube." He fooled me again. The emperor asked him to finally figure out what was in the box, so he gave him a name, Yellow Toad. The emperor shouted, "Yes, it's a yellow toad." He passed the exam again.

I got it on Baidu again.
