Translation of the title

"Dark Blue Space "Nebula-M" 1 "Jump" low-altitude vertical recovery flight test was a complete success."

Press release from Deep Blue Aerospace (in Chinese) http://www.dbaspace.com/newsthing_s.html?n_id=24
Extract
"While Deep Blue Aerospace is conducting a complete analysis of the data of this test, the "Nebula-M" rocket No. 2 test prototype is in the company's assembly plant in Nantong, Jiangsu, and is quickly undergoing assembly and testing. At the same time, the company will continue to implement 100-meter-level low-altitude flight and high-altitude vertical take-off and landing flight tests in 2021. At the same time, Deep Blue Aerospace’s main product "Nebula-1" into orbit rocket has completed the prototype production and strength test of a sub-level rocket body structure last year, and the orbital level launch and vertical recovery test will also be gradually implemented as planned."

100 m VTVL test successfully completed. Looks like it lands right back on the trench:

Nebula-1 orbital launch vehicle now planned for first flight in 2023:

Deep Blue Aerospace conducts 100-meter VTVL rocket test [dated Oct. 13]

Quote
The test is part of the development of the 2.25-meter-diameter Nebula-1 orbital launcher, with a planned first flight in 2023. The Nebula-1 is to be capable of lifting 500 kilograms to a 500-kilometer Sun-synchronous orbit.

So is Nebula-M the test vehicle (not orbital) and Nebula-1 is the 500kg to orbit? Does the larger rocket have an announced name?

And is the first stage VTVL recovery just for the larger rocket or also Nebula-1?

Someone is going to be next to reuse.  Maybe Rocket Lab.  Then China?  Before ULA or Blue Origin or Russia or Europe?
