Doesn't work. I live in Hong Kong, which has some of the world's most efficient public transport systems. People don't actually talk. They just look at their phones. A train cart can be full of people but no conversation.
Hi, I am the emperor of the Qin dynasty (207 BC). I am not actually dead because I found the medicine of immortality. I want to rebuild my empire but I currently don't have any money. Can you send me a few liang (兩, Chinese mass unit) of gold to get started? I must heavily reward you when my empire thrives again.
