Yes, it is. The relevant law/regulation is cited in my answer to Does tourist visa (90 days) apply after a long-term visa ends in Schengen countries? (that question was about someone who does not need a short-stay visa but the answer also applies to your situation).
Unfortunately, it's easier to benefit from that if you don't need a short-stay visa because you might need to go back to China or some other place where you have the right to reside and wait for the visa there. Worse, not having a stable job or life in China (if that's your case) would work against your application.
I don't think you can generally apply for a short-stay Spanish visa in Spain (or, actually, from any Schengen country as you typically need to prove you are a resident in the district covered by the consulate to which you apply and if you are already a resident in the Schengen area, you don't need a short-stay visa).
So the 90-day limit is not a problem but getting a visa might be, for unrelated reasons.
