Zhihuitianwang-1 01 is the first satellite of the Zhihuitianwang (Skynet-1) constellation, which is a broadband communications constellation first proposed by the Tsinghua University. The constellation will eventually be expanded to 32 satellites covering the entire globe. It will also provide space-based backhaul service for future 6G networks.
Zhihuitianwang-1 01 is equipped with a engine for orbit control, which is the first for China. The engine has been performing as designed.

A hot test run on four YF-100K engines (staged in parallel) was carried out successfully. The total thrust exceeded 500 tons, which is the highest China has ever attempted in a hot test run. The test verified the first stage performance of the Long March 12 launch vehicle, which is scheduled to fly for the first time later this year.
Long March 12 model revealed.

The private rocket engine maker Jiuzhou has revealed that it is participating in "a national program for developing next generation of rocket engines". Not sure what this entails. Jiuzhou's product portfolio currently includes the Lingyun and Longyun LOX/Methane engines.
The image shows a list of proposed projects for Wuxi Aerospace Intelligent Manufacturing Park. Jiuzhou has plans for a 20,000-square meter production plant for a certain 200-ton LOX/Methane engine. This could be the next generation engine Jiuzhou previously alluded to.

Two updates on the Hainan Commercial Spaceport.
1) The sound suppression system tower for launchpad no. 2 has been capped. The installation of water tanks will commence immediately.
2) A test filling of the 120-cubic-meter liquid nitrogen storage tanks (part of the rocket fueling system) has been successfully completed.

The strap-on booster version of CZ9 that comes later will be much stronger; this one is nothing special.
This version is actually quite ugly, a bare big cylinder has nothing much to look at. Especially the first stage is short, have you noticed that the first stage is almost the same height as the first stage of CZ10 next to it? In other words, the booster of CZ10 can also be modified for use with CZ9. The ugliness of the bare CZ9 is comparable to that of Starship V3. Why? It's because the first stage is actually a bit short. In fact, China can make it longer, but they didn't make CZ9 taller, the reason is to leave space for the upper strap-on. There will not be a CZ9 strap-on plan before 2040.
The CZ9 3rd stage has also been greatly modified, using a single engine. This is the most interesting part. The second stage is likely still to be hydrogen-oxygen.
The 2nd and 3rd stages of this CZ9 can still be enlarged and improved (lengthened), this is the key.
