Drill straight through the center of the Earth from Ho Chi Minh City, Vietnam and you'd surface on the exact opposite side of the planet — its antipode.
Ho Chi Minh City's antipode sits at 10.82°S, 73.37°W, in the southern hemisphere, west of Greenwich. That places it in or near the Pacific Ocean.
It lies roughly 20,015 km from Ho Chi Minh City — about as far apart as two points on Earth can possibly be. And the relationship is symmetric: the antipode of that spot is, of course, right back here in Ho Chi Minh City.
Ho Chi Minh City's antipode is a rare one: it actually lands on solid ground, about 5 km from Nueva Vista Villa Sol, a hamlet in Peru. Most cities don't get that lucky — antipodal land pairs are uncommon since water covers about 71% of the globe.
