Archaeologists in north China's Shanxi Province have discovered an ancient canteen that is believed to have been used during the Battle of Changping (262 BC).

The Battle of Changping was one of ten decisive battles that would reshape the country's central region during the Warring States period (475-221 BC).

The canteen is believed to date back to approximately 2,200 years ago and is located between the city of Gaoping and Lingchuan County in Shanxi Province. It is located north of the Qinling Mountains in close proximity to the Bailishi section of the Great Wall.

The canteen is believed to have been used by soldiers who were camped out while fighting during the Battle of Changping, which pitted the states of Qin and Zhao against each other.
