The word hypergolic doesn't mean that, but in spaceflight the term refers to a fairly specific group of compounds; Dinitrogen tetroxide and unsymmetrical dimethylhydrazine or monomethylhydrazine (UDMH / MMH).

mmh+nto is the only thing still being used in the west outside of missiles. even spacex use it for module maneuver. I think. not even sure why I know that.

but china probably use the lesser hypergolic combinations for actuall lift off.

Yep, Long March 2, 3 and 4 use YF-20 engines (and its derivatives) which are UDMH-powered.

They're switching to LOX/Kerosene for LM5.
