A leaked video has found its way online after a lady in Shenzhen is caught on camera for pooping in a lift on the Shenzhen metro in a very unladylike manner.

The incident took place on April 22 in the middle of the afternoon, on a typical day, with travelers walking by in the background.

The man and woman duo work seamlessly as a team, as he keeps a lookout for any unsuspecting people who stumble across their act to ward off any embarrassment.

The woman makes a mess inside the lift, leaving it for a cleaner to deal with.

Some eagle-eyed netizens have taken to Weibo in the past to publicly name and shame those who have no regard for themselves or others around them.

A similar incident happened around two months ago on the Guangzhou metro when a high-school teen was happily using a trash can to empty his bowels without objection by the staff in the station.

Last November a boy was caught short on the train, and crouched down beside the door to relieve his bowel while his dad stood by.

However, in more recent times, we’ve had a mother letting her son poo in the middle of the airport terminal in Taiwan, and in February, a child was having a poo in the middle of an airplane aisle mid-air.

What do all of these incidents have in common? They are all related to transit. Perhaps this is symbolic of what China thinks of its subway, rail, and airplane services.
