Up to 200,000 young people rented bikes - which cost as little as £1.51 a month - to travel from Zhengzhou to Kaifeng for soup dumplings as part of a Chinese social media trend.

Making the impromptu five-hour ride between two Chinese cities became a craze among young people. But as their numbers swelled, the authorities shut it down.

A night-time cycling trend that started with four Chinese students riding 50km for dumplings blew out to a reported 100,000 people on Friday, jamming major roads, overwhelming a small tourist city and drawing the attention of authorities.
