"Xiao Yu shouldn't either! Xiao Yu, don't listen to him. If you're sick, you need to take medicine right away; otherwise, what would you do if a minor illness turns into a serious one?"
"Uncle Zhang, I'm educating Xiao Yu here. What are you meddling for?"
"Educating what? You think reading a few articles makes you an expert? There's a lot of unreliable stuff on the internet. Oh, you don't need medicine for a cold, then what's the point of cold medicine?"
"You only know what happens, not why it happens. We're no longer in an era of treating only where it hurts. We need to establish a more scientific worldview for this generation's children!"
"Oh? So you're teaching kids not to take medicine when they have a cold? That's just foolish!"
"Uncle Zhang, your thinking is too traditional. Our educational philosophy needs to keep up with the times!"
