We have scramjet powered ones, we have oblique detonation powered ones, we have TRCC combined cycle powered ones, we have TBCC combined cycle ones, we have rotation detonation engine powered ones.
Here are just a few images of Chinese ones that are not powerpoint image renders.
Tsinghua University's experimental rotation detonation engine. This is just an academic project and PLA's RDE powered hypersonics would be secretive. Can see more RDE of this public project from this
website.
another university project of flying combined cycle I think this one was a TRCC.
According to both China and the US governments, China has flow a mach 20 (average speed) hypersonic vehicles with range that circumnavigated the Earth.
US General has claimed in the past that China has flown hypersonic glide and powered vehicles
"hundreds of times" since 2000s.

In this short clip, one can see an engine kick in. Two seperate stages at least shown in the short clip.
Another hypersonic cruise missile with scramjet stage kicking in, very clear difference between the stages. Latter stage has extremely strange contrail without the usual turbulence patterns of usual rocket contrails blowing around.
DF-100 scramjet powered hypersonic "cruise missile" was in service before 2019. Starry Sky project was just some more publicly shown thing similar to DF-100 at least in engine and intake type for that type of scramjet.
DF-17 obviously and DF-17 clearly has some exhaust control systems that are part of flight controls.
A lot more in Pentagon and US papers. More in Chinese literature reports, official and leaks from presentations and meetings.
Sodramjet is oblique detonation engine. Also a major one possibly better for larger vehicles.
CASIC's combined cycle engine at least a really old photo that has been revealed to public.
There's a jet fuel powered one that can reach mach 9. Kerosene powered engine (most likely as one section of a combined cycle engine) that can reach above mach 5 for sustained speeds. So many projects almost all only hinted on with few details online community can piece together using what is reported and written by the US in government and military papers and what news come out from both sides with only just whispers and occasionally some information such as slides, pictures video of distant flight captured by civilian.
