"Mr. Wei, I see that you haven't eaten your chicken wing. Do you want to trade? I'll use streaky pork to trade with you." Wang Hong said.
Mr. Wei's eyes flashed with surprise, and he looked at Wang Hong with suspicion,"There were really iron-headed people?
"No problem. We'll change like last time." Mr. Wei's face was as usual, showing a helpful expression.
"That's not right, Mr. Wei," Wang Hong said."I realized that there was a problem with the way we switched our positions last time."
"Oh?" Mr. Wei was curious and asked,""What's the problem? I'm listening. "
"It's like this, Mr. Wei, last time you asked me what I would be willing to use to exchange for chicken wings, but in reality, this kind of comparison is wrong. " "Because chicken wings aren't Mr. Wei's favorite, so this exchange isn't fair," Wang Hong explained.
