What else? I only know about df-100He's not talking about DF-ZF.
China does have something hypersonic that sustained an average speed (across the globe) close to mach 20 with top speed probably at, around, or above mach 20. At least if US government statements are anything to go by.
DF-ZF is far from the only Chinese hypersonic "thing" out there. However it is the only one China was okay with letting the public photograph it without any restraint... well at least from a distance and limited angles.
