Did they bring new suits aboard Tianzhou everytime they launch new astronauts? I only recall they brought a new extra suit with yellow strip.

Long March9 first launch in 8 to 10 years and prototype has already been built.

Short-duration hot fire tests of all 3-stage engines have been conducted

Didn't notice your post until now.

I must say that this is a surprise. Long Lehao is playing us.

From his wording, engines of all 3 stages have conducted full system test. However we don't know exactly which engines are they. This is what I gathered from open reports. Green means full system hot test, Blue means half system (turbine, GG combined) test. A full YF90 was assembled in 2021 but never heard it conducting full test.

CZ-9	2011​	2021​	20220917​	2022​
1st stage	YF130	YF135	240t LOX/Kerosene	200t Methene
2nd stage	YF90	120t LOX/LH	120t LOX/LH	120t LOX/LH
3rd stage	YF79	120t LOX/LH	120t LOX/LH	120t LOX/LH

Two possibilities

1. Long Lehao was talking about 2011 version of CZ-9 if CASC did not withheld information from the public regarding engine tests.
2. There are more engines completed full test than CASC has shared with the public.
