I asked you to evaluate a kitchen knife. Would you use it to chop an engineer shovel?

Zhao Feng traveled through a parallel world and became a live broadcaster. He sold kitchen knives for a week in a row. For six days, no one paid attention to them. Not only that, fans in the live broadcast room also ridiculed him, saying that all the goods sold by the host were It's garbage.
Hearing this, Zhao Feng couldn't bear it anymore.
In front of hundreds of people in the live broadcast room, he took out an engineering shovel. Didn't you say that my things are garbage? Now I will let you see if they are garbage.
"Bang bang bang..."
The kitchen knife struck the engineer's shovel and countless sparks shot out, and there was silence in the live broadcast room.
After a while, countless barrages appeared on the public screen.
"Qiao Li, who taught you to test a kitchen knife like this?"
"What a sin! I'm afraid a good kitchen knife will be destroyed!"
"I asked you to test a kitchen knife, and you use it to chop an engineer's shovel? That's crazy!!!"
…
Gradually, Zhao Feng's weird testing methods were spread to the Internet, causing an uproar. Suddenly, he became popular, completely popular.
Not only that, people suddenly discovered that this anchor was not only ruthless about testing products, but also the entire industry of live broadcasting with goods was exposed by him.
