A Chinese toddler travelling with his parents and grandparents defecated on his seat aboard Delta Airlines as they traveled to Beijing from Detroit, according to Chinese media.
The parents allowed the toddler to answer nature's call as they put newspaper on his chair and have him go right there and then - much to the horror of other passengers.
Other passengers pleaded for the parents and crew to have the toddler finish his thing inside the cabin toilet, but the toddler's grandparents were adamant.
Once the boy relieved himself, the stink quickly spread the cabin and completely disgusted fellow travelers, passenger Luolan Gang Wang told Sina News.
The couple had since suffered backlash among fellow Chinese for shaming the country. The parents now claimed that they are being discriminated.
A report from the Daily Mail said that the parents and Delta Airlines were not available for comment to deny or acknowledge the reports.
Chinese travelers had been notorious for their weird travel etiquette - refusing to switch off mobile phones and traveling drunk - that even the Hong Kongers were condemning them. Mainland Chinese tourists were infamous for their unruly social etiquettes.
In 2013, a Chinese teen was condemned for vandalising a 3,500-year-old temple in Luxor Egypt with a note that said , "Ding Jinhao was here."
A travel blogger discovered the vandalism and posted a picture of it on a Chinese social media site, posting that he was so embarrassed about his countryman that he wants to hide himself.
The Chinese teen had also suffered backlash from Chinese netizens. The boy in the centre of the controversy was reportedly traumatised.
Responding to the growing criticism against Chinese people behaving unacceptably during travel, the Chinese government had come up with travel guidelines created with the National Tourism Administration.
The guidelines underlined rules against littering, spitting and fighting in queues.
In Beijing, a school on etiquette with curriculum fashioned after Swiss finishing schools was opened in 2014. The school aimed to teach good manners and classy behaviour while travelling aboard.
