One more private launch provider that I haven't heard of until now. The company is called AstronStone (宇石空间). It's currently developing the AS-1 (AstronStone-1) launch vehicle, a reusable LOX/Methane rocket of stainless steel construction with chopstick recovery. I have no information on its dimensions and performance parameters.

The rocket is likely to be a 4-meter-class rocket with a diameter of 3.7 to 4.2 meters. The technical lead is Dr. Tang Wen, who previously worked at the China Aerospace Science and Technology Corporation and was involved in the development of the Long March 5 (CZ-5) and Long March 7 (CZ-7) rockets.

I don't think they are using them for cooking.​

China test-fires 5 new rocket engines in a single day. But what are they for?​


China's state-owned main space contractor tested five different rocket engines on one day last week in preparation for future missions and projects.
The China Aerospace Science and Technology Corporation (CASC) tested the engines at two sites in Beijing and Laiyuan County in Hebei Province, north China, on Jan. 2.
One test-fired a new hydrogen-oxygen engine for the upper stage of an unspecified rocket for 100 seconds. It was conducted by the 101 Institute of CASC's Academy of Aerospace Propulsion Technology.
"The just-completed experiment tested an upper-stage liquid hydrogen-liquid oxygen engine. It tested the overall coordination of the engine and obtained performance data. After assessment, we concluded that the test was a complete success," Xia Wei, a CASC engineer, told China Central Television (CCTV).
