Beijing: If a 14th century painting is to be believed, people in China have been using a refrigerator-like device since that time.

Archaeologists in north China's Shanxi province uncovered a 700-year-old mural dating back to the Yuan Dynasty (1279-1368) that depicts what appears to be a refrigerator, Xinhua reports.

The mural shows servants preparing a table with vases and drinking vessels, demonstrating the luxurious lifestyle enjoyed by royal family members at the time.

Pictured beneath the table is a wooden box filled with ice, which is believed to have been used to keep food cold before being served, said Chai Zejun, a researcher with the provincial archaeological institution.
