单集简介 ...

What if the thing you toss without thinking outlasts you by four centuries? That is the tennis-ball problem. Millions of them, every year, destined for centuries in a landfill. But in Qingdao, they have found a fix. The solution came from 20,000 dead balls reborn as a court you can actually play on. This is the story of waste that won't wait 400 years to disappear. / A viral complaint is sweeping across China right now. Professors and employers are frustrated because their students and young hires cannot write a proper email. Subject lines are missing. Greetings are absent. Sign-offs are nowhere to be found. But these kids grew up on messaging apps, where speed always won and formality never mattered. So who is really out of touch here? Them, or the rest of us? (33:11) On the show: Steve, Yushan & Yushun

  • discussion keeps the world turning.

  • This is Roundtable.

  • Think about something you throw away every day without a second thought.

  • Now, imagine that thing takes 400 years to disappear.

  • That's the reality with tennis balls, and we go through millions of them.

  • But there's some good news.

  • In Qingdao, they've figured out how to turn 20,000 dead balls into something that you can actually play on.

  • We'll tell you all about that today.

  • And then...

  • Imagine a college student who's never sent a formal email in their entire life.

  • They grew up on WeChat, on DMs, on messages that start with hey and end with nothing.

  • And then one day they're expected to email a professor or a company and no one ever taught them how.

  • Well, that's driving professors and employers crazy.

  • The issue of young people not knowing how to write an email has gone viral in China.

  • But is it their fault?

  • Coming to you from our studios in Beijing, this is Roundtable.

  • I'm Steve Hatherly.

  • Thanks for joining us this episode.

  • And for today's show, I'm with Yushun and Yushan.

  • Yushun and Yushan, good afternoon to you both.
