A: Huh. Why are you holding a bamboo scroll?  

B: Haha! I want to tell you a story today, and it’s all about “paper”!

A: Wow, that really is important! If we didn’t have paper, I wouldn't even be able to do my homework right now!

A: Look at this! Someone is saying that a certain district will have its water supply suspended for a whole week tomorrow. A ton of people actually believed it and are rushing to panic-buy water!

A: I get it now! Let me report this fake news right away!

B: Exactly! From “paper” to “smartphones,” the messages we pass along must always be the truth!
