Parent misspoke. It's been 21 lines consisting of 516 stations in total since inception (really since 2000 since there was a long lull of little activity in the 90s). The discrepancy in lines comes from whether you count certain rail-based transportation lines as part of the subway system or not. The discrepancy in subway stations is mainly due to whether you count interchange stations as single stations or multiple stations. I think the former is the one that is usually quoted for other subway systems in the world so makes more sense (so ~400 is probably the more appropriate number of stations to state).

I also wonder if the Wikipedia article may be out of date? IIRC there were some new stations added in the last few months. But even if that were the case it's just a couple of stations, so the numbers should still be close.

More impressive to me is the pace of construction in smaller cities which have also been rapidly building out subway systems (e.g. Hangzhou comes to mind, getting around Hangzhou on public transportation has drastically improved in the last five years, likewise I've personally seen the same immense improvements for Harbin).

Ah, that makes some sense.

Like in San Francisco, there is the regional BART light rail, but also there is the hybrid bus/rail Muni metro transit for local service.
