The early morning.
A subway station exit in Shanghai.
A man in a suit took out his mobile phone and was about to order a ride to the office. However, after opening the app, he was surprised to find that there were no cars nearby.
"That's strange, why are there no cars available?"
Are there a lot of people taking taxis today?
The man standing next to him spoke with a smile.
"Have you not heard? A conference is going to be held these few days. The main roads in the second ring are basically closed."
"The roads are closed? Why didn't I know about this?"
"There was a text message notification, did you not pay attention? Haven't you noticed there are no cars on the highway?"
The man in the suit raised his head and was shocked.
"Oh f*ck true, not a single car?!"
"Of course. Just wait for the bus honestly."
