Passengers must act civilly on subways

A 17-YEAR-OLD MALE passenger on a subway train verbally abused two young women trying to persuade him to scan a Quick Response code. The police later caught the youth involved. Beijing Youth Daily commented on Monday:

The behavior of the male passenger was unruly and disrupted public order. the police have warned people to behave civilly and obey the rules when travelling on the subway.

But what were the two girls doing? Some said they were trying to promote a startup; others suggested it was part of a scam.
