According to ClutchingMyTinkle, when he was in China, he politely stood five feet away from a person taking out cash.
But other people soon stepped between him and the ATM until he was last in line.
In fact, he said, they were queuing so close together that they were basically touching.
Another user, pchiu, advised that this was perfectly normal and that you should just tell the line cutter that you're already waiting and they would generally move to the back of the queue.
One of the most frequently mentioned surprises was how foreign travellers get mistaken for or inadvertently become celebrities while travelling in China.
According to KommandCBZhi, while he was living in China, he was frequently asked whether he played for the NBA because he was so tall.
Many of those who stopped him would also request to have their pictures taken with him.
But popularity soon got the best of him.
He wrote: 'I'm quickly swarmed by tons of Chinese people who want to take a picture with me...
'That is until I was asked to leave because the group around me was getting so large it was blocking the entire span of the wall and people couldn't get past.'
For InfernalWedgie, it was Shanghai's Marriage Market that surprised him.
There, hundreds of parents walk around with leaflets and photographs of their offspring, hoping to match them up with prospective suitors.
He commented: 'It was like seeing the floor of a busy stock exchange.'
Many were also surprised by the liberal toilet policy in China, especially involving the nation's children.
Reddit users like Beauty_sandwich were unprepared when they were met with the sight for the first time, especially when it was being used in a public space.
She wrote: 'When they have to go, be it on the street, in a store, or on a bus, they just crouch down and let it flow.'
While the myriad of complaints about bizarre sights in China totals the thousands, many were also quick to say that they would return in a heart beat.
