It's a common source of confusion. The administrative definition of a 'city' is the equivalent of its metropolitan area + all satelite 'towns' and their suburbs (including farm lands).

My hometown has a population of 3.4 million (prefecture level city or 3rd tier as people call it). But it has an area about 6000 km^2, easily reaching the total size of London. At its core the central town has roughly a population of 700,000. And there are 4 more towns after the central one, each has smaller villages and suburbs under them. People living in these towns wouldn't consider they are living in the same city.

Forgot to add context, my hometown is under zhejiang province (as different regions have different population structures).

I got the area wrong. Greater London is apparently 1500 km^2 so the total area of my administrative city is 4 times the size of that (with a total population of 3.4 mil)
