On November 15, 240 gathered at a shopping center in Baotou City, China’s Inner Mongolia province, to take part in an unusual competition inspired by the ‘lying flat’ movement. “Lying flat” is a popular internet slang term in mainland China that describes a lifestyle of giving up on the rat race of reaching societal expectations and instead relaxing and choosing to maintain a minimum standard of living.

The rules of the competition were fairly straightforward: contestants needed to lay flat on a mattress, and while they were allowed to roll around on the mattress, read books, eat, or use their smartphones, they were not allowed to get up from the mattress or even use the restroom. The last person to remain lying flat would be declared the winner.

Although there was no time limit for the contest, over the first 24 hours, 186 competitors had been eliminated. Those who remained on their mattresses agreed to stricter rules being gradually introduced, and after 30 hours, only a handful of people remained in the competition.

At the 33-hour and 9-minute mark, only 3 contestants remained in the lying flat contest. Two minutes later, one was eliminated. The remaining 2 contestants lasted for over 20 minutes, and finally, at 33 hours and 35 minutes, one of them gave up, and the other was pronounced the winner.

Chinese media reported that the winner of the Baotou City lying flat contest wore diapers to avoid having to go to the toilet, but so did many others who entered the competition, so he wasn’t disqualified or penalized in any way. He ended up winning 3000 yuan ($420), while the second-place winner took home 2000 yuan ($280), and the third-place winner 1000 yuan ($140).

The lying flat contest was reportedly a big hit in China, with tens of millions of people watching the livestream over the 33 hours and 35 minutes.
