Dozens of residents have been woken up in the middle of the night by a loud snore that shook a small neighbourhood in China.
A video taken by one Chinese resident shows a few flats having their lights switched on while a rumbling sound passes around the apartment blocks.
It appears that the security guard has fallen asleep while on the night shift and accidentally turned on the public address system.
The person who filmed behind the camera can be heard laughing hysterically as they pan it from the window.
The post suggested the incident took place at a neighbourhood in Chongqing, one of many Chinese cities that has been put on lockdown.
There are 400 confirmed coronavirus cases and two deaths reported in the southwest Chinese municipality as of February 6.
Web users said the video come as a "comic relief" to the coronavirus-stricken city as one said: "Things happen. Look at the funny side."
Another one wrote: "Great for the morale! To hear people laughing!"
The pneumonia-like virus has spread across all provinces in China and to 24 other countries.
Residents in the quarantined cities were monitored by drones after local authorities made it mandatory for the public to wear face masks.
Earlier this week, a Chinese student and his mother were confirmed to be the first two cases of coronavirus in the UK.
They are being treated at the specialist Airborne High Consequences Infectious Disease Centre at Newcastle’s Royal Victoria Infirmary (RVI) hospital.
A spokesman from the University of York said: "We are monitoring the situation closely and we continue to provide as much advice, care and support as we can to our University community.
"If people have any concerns about their health in relation to suspected coronavirus we ask that they follow current PHE advice and contact NHS 111.
"The University has set up a call centre over the weekend for anyone who has any further concerns or inquiries. The telephone number is 01904 809571."
