From Xinhua,

China's space tracking ship Yuanwang-3 departs for new monitoring missions.

Commissioned on May 18, 1995, Yuanwang-3 is a second-generation Chinese space tracking ship. It has undertaken more than 90 maritime tracking and monitoring tasks for spacecraft, including the Shenzhou spaceships, Chang'e lunar probes and BeiDou satellites.

Located at about 29.5° N. I wonder if this will be where they plan to launch CZ-9.

No, this place would only used to launch commercial rocket from SAST and CASIC. CZ-9 would launch from a planned artificial island in Wenchang.

Thanks tangdou8. How do you know that CZ-9 is launching from Hangtian island? Is that the artificial island? What does the text on the drawing say?

As you can see on the satellite image, the island does not exist yet. You can compare the geographic feature of the drawing and satellite image to get a vague location of the artificial island.
There is no official word on launching from that island, but the well-known insider on weibo called "汤婆婆" once confirmed this assumption. Also, by calculating the safe distance required by CZ-9, it is logical to launch from that island as it is farther away from the populated area.

Moreover, CASC signed memo with local government regarding to CASC' Hainan sector in Wenchang. In the rocket manufacturing and testing part(航天重大工程总装总测基地), which could correspond to the relevant location shown on the drawing, CASC states 'constructing the assembly and testing facility for super heavy launcher and new generation manned launch vehicle and large ground testing equipment' 论证、布局重型运载火箭、新一代载人运载火箭总装测试基地和大型地面试验设施,以航天重大工程带动海南航天基础配套能力

China is developing plans for a 13,000-satellite megaconstellation

https://spacenews.com/china-is-developing-plans-for-a-13000-satellite-communications-megaconstellation/

Factually there has been recently only 2 pieces of news on Chinese constellations:
Published on March 7 "A national network (guowang) corporation will be set up to coordinate planning and operation of Internet satellite construction"
Published on April 19 "Hongyan and Hongyun constellations will undergo major changes"

The rest is just speculation

China pushes forward exploration of small celestial bodies.

China is pushing forward its exploration of a near-Earth asteroid and a main-belt comet with one space probe, said a senior space expert on Saturday.

The Chinese are wonderful followers.  Show them how to do something, and they will figure out how to do it better.  The Japanese were very good at doing that, too, back in the day.

China is planning to develop suborbital point-to-point transport in the coming decades. Its solution looks shockingly like SpaceX's Starship.

You do realise this is just a video, not the actual thing?

Apparently they want to translate "Guowang" as "State Grid"
