Probably a whiteboard or some other removable surface. They needed a hard surface to sign the space station transfer documents seen in the second image.

Some images of the Space Application Engineering And Technology Center where various apparatuses for space experiments used onboard the Chinese space station are tested and developed. In the 1st image, on the right, you can see various payload adapters for mounting experiments on the exterior of the space station. In the 3rd image are experiment cabins for the interior of the station. Also check out the fancy large transparent displays (1st, 3rd, and 4th image).

Jiuzhou's product portfolio currently includes the Lingyun and Longyun LOX/Methane engines.
The Lingyun LOX/Methane engine is the first liquid rocket engine developed by Jiuzhou for the commercial launch market. It is also the first liquid engine in China designed for reusable rockets. The engine has accumulated more than 10,000 seconds of hot test runs and was used in a successful VTVL test vehicle by a certain launch provider.
Ground thrust: 100kN
Vacuum thrust: 116.5kN
Ground specific impulse: 288s
Vacuum specific impulse: 355s
Weight: 248kg
Maximum swing angle: ±8°
Variable thrust range: 20%-105%
Number of re-starts during a single flight: ≥3 times
Single-mission burn time: ≥500s
Reusability : ≥50 times
The Longyun LOX/Methane engine is a reusable high-thrust engine designed for medium to heavy launch vehicles. Its thrust-to-weight ratio exceeds 80 at sea level. The engine has accumulated 7,000 seconds in hot test runs. Longyun has been selected by a certain private launch provider (almost certainly Arrowhead/Space Epoch) to power its reusable rocket (XZY-1) currently under development, which will conduct a sub-orbital flight and sea recovery test later this year.
Ground thrust: 676kN
Vacuum thrust: 704kN
Ground specific impulse: 290s
Vacuum specific impulse: 350s
Weight: ≯850kg
Maximum swing angle: ±8°
Variable thrust range: 32%-106%
Number of re-starts during a single flight: ≥3 times
Single-mission burn time: ≥200s
Reusability: ≥50 times

Yet another new space tourism company. Co. was co-founded in 2023 by TV host (雷诗情) and Hong Jianwu (洪建武), and many of its current personnel have previously worked for China's manned space program. Interstellor is currently developing the CYZ-1 sub-orbital spacecraft that can carry seven passengers. The company aims to first launch the spacecraft (unmanned mode) in 2026, with the goal of commencing commercial operations by 2028. The ticket price is set at three million RMB, and the first customer signed up in November of 2023. Interstellor has signed a cooperation agreement with a certain unnamed launch provider to launch the CYZ-1 spacecraft.
A team from Interstellor recently met with the Director of Wenchang Space City to discuss possible cooperation:
