But a fascinating map has revealed that most populated places on Earth have an opposite point somewhere in the ocean.
The interactive Antipodes Map lets you check any location on the surface of the planet to check where it's opposite point is.
The Chinese are among the relative minority of countries who would strike land if they were to undertake this enterprise, according to the website where you can try out the tool for yourself.
Digging a hole from the centre of Beijing, you would emerge in Rio Negro, near Bahia Blanca in Argentina.
Other major or capital cities that are close to being antipodes include Auckland, New Zealand, and Seville and Malaga in Spain.
Exact antipodes include Ulan Ude in Russia and Puerto Natales in Chile.
The two largest inhabited antipodal areas are located in East Asia, in China and Mongolia, and South America, in Argentina and Chile.
"The Australian mainland is the largest landmass with its antipodes entirely in ocean," the Antipodes website writes.
"The majority of locations on land do not have land-based antipodes."

The largest antipodal land masses are the Malay Archipelago, which is opposite the Amazon Basin and adjoining Andean ranges.
Given that the surface of the earth is around 71 per cent water, it's probably unsurprising that the chances of hitting land are relatively low.
An American digging a hole from Times Square in New York would end up in the ocean off the coast of Australia.
Brits wouldn't fare much better, with a tunnel dug from under the Houses of Parliament finishing up off the coast of New Zealand.
Japanese tunnel diggers starting in Tokyo would surface off the coast of Uruguay.
And Russians digging from Moscow would find themselves in the middle of the Pacific Ocean.
There are no non-stop scheduled flights between any two antipodal locations by commercial airline service.

But a hypothetically perfect antipode flight would be Tangier Ibn Battouta Airport, Morocco to Whangarei Aerodrome, New Zealand, a flight of approximately 12,500 miles (20,000km).
The North and South pole are, by definition, antipodes.
Scientists have previously calculated the journey time, were tunnel diggers to make it all the way through the Earth's core and out to the other side.
Research has previously found that it would take a person 38 minutes to fall from one side of the planet to the other.

The latest time estimate was calculated by Alexander Klotz, a graduate student of physics at McGill University in Montreal, Canada and published in The American Journal of Astrophysics.
Originally it was believed that this would take it would take 42 minutes and 12 seconds to fall through.
But the hypothetical scenario, published in 2015 scenario, found that when the different densities of Earth's layers are taken into account, the trip is four minutes shorter than predicted.
