Space lettuce.
A published paper: On orbit events of long-term operation of space station and overall planning of spacecraft access by Zhang Jiacheng, Zhu Yuehe and Luo Yazhong mentioned that the launch price of Shenzhou crew ship and Tianzhou cargo ship to be CNY ￥850m and ￥350m each, about USD $123m and $51m.《空间站长期运营在轨事件与飞船访问统筹规划》张嘉城 朱阅訸 罗亚中

huh, they failed to reach orbit three time but are testing a 100t metalox engine!!
Highly likely a variant of engine from CASC 4th academy that was successfully tested in 2019. That engine was 2.65m, 200t thrust, fuel 71t. Orienspace is a company established in 2020, nobody can make such engine from scratch within little more than one year.
It seems that CASC is constantly using shell companies for commercial market. I put my word here, the 500t single piece SRB CASC tested in 2021 was meant for commercial use as 1st stage, I won't be surprised if this one shows up under another name.
failure is the key of success. this time they came up with proper planning and i m sure next launch will be successful. eagerly waiting for the launch.

CZ-7A also replaced by CZ-7B ?I read this presentation (April 2022) again. There is an ironic twist. There was a time not long ago that people are saying that CZ-7 series will only have the 2 stage variant for cargo launch to the space station while most other jobs are done by CZ-8 series. It seems that number 8 will be the short-lived one as the slide says that both 6 and 7 will be replaced by 7B,C,D.
One thing to note is that CZ-7C is essentially CZ-8 with elongated 1st stage, CZ-7D is CZ-8A elongated, plus the new 2nd stage with one YF-75E replacing two YF-75.
As I always say 6,7 and 8 are all 7 from the beginning, and maybe will end up in 7 in the end. It is just a number or letter, no big deal. But Long Lehao does do a good job to keep us confused.

Based on this roadmap, next test will be the AT-1B launching the orbital space plane as a full-up stack.
