there's a lot of incentives pushing people into EVs. For example, to limit pollution and congestion it often takes winning a lottery to get a car registration for ICE, but that's generally much laxer if not completely gone for EVs.

In Shanghai at one point the cost of a ICE vehicle registration cost more than a low end EV.

Beijing has a lottery for plates instead, except the allocation for EVs is separate from ICEs, so it is much easily to get an EV. Back in 2016, you started seeing Model S’s driving around Beijing, and those were definitely imported with something like a 20-30% tax (at least), but the only alternative was no luxury car (like the famous black Audi that used to be super common), so they just started showing up.
