missing a no of variables. Keep in mind right now both 921 and CZ-9B exist on paper basically. The only guys who know about those info are the designers, which Long Lehao as a veteran rocket designer, obviously has access to.One thing that can be quite certain is 921 is lifting a page from Falcon 9, or Falcon heavy to be more precise. I suspect once VTVL is successfully tested on CZ-8R, they're going to apply it to 921, then to CZ-9 21 edition.
