Chinese DF-17 Missiles Operational?

I think CCTV snuck DF-17 stock footage into a December 2019 broadcast ostensibly about other missiles.

If true, then regardless of if they have hit actual IOC, then they are at a minimum probably doing training ops/drills. pic.twitter.com/pbNkmYfn2A

That's quicker than expected.  Thought this was near future, not now.  Calculations need to change.
