With that resolution Perseverance would be around, a pixel?
Is it possible that they publish a picture of it in future or would it be considered “politically nosy”?
roughly 2 X 5 pixels.
Why would taking a picture be nosy? MRO has taken pictures of others' hardware on Mars and LRO on the Moon. Why should Tianwen not do they same?
Of course they will take it, just for calibration or maping purposes. I'm just asking if publish them would be understood. Don't want to start a discussion here, but press and media, so more interested in gossiping than science, may show it more like being "spied" or China nosyness, which Chinese may not want. (you know, the press guys)

Doubt that would happen - LRO has been taking photos of the Chang'e landers on the Moon for a long time and the Chinese are very happy to see their hardware being snapped photos by the US, the same would happen for MRO and TW-1. And as someone who have been following their own spaceflight forums I can assure you that they are probably more sensitive to such matters than the typical US space enthusiast and they are actually happy with photos taken; why would the US press be even bother with this?

These links are related in a ways to the current space program, in other threads we have posts where they talk about a manned direct to Mars mission. Robert Zubrin style?
Their websites and media have been following other NASA spacecraft and other Martian missions

http://tech.sina.com.cn/d/2006-03-28/0856879718.shtmlTalk of a manned mission
The undertaking will confront enormous challenges. The journey could “take more than 500 days,” according to Pang, and might not come to fruition before 2050. And then there are other threats, like “the decrease of bone mineral density, space radiation and mental health,” Pang added.
https://futurism.com/the-byte/china-plans-send-astronauts-marsScientists have been making preparations for the country's manned lunar missions, including the establishment of a manned scientific outpost, according to the nation's leading space contractor, China Aerospace Science and Technology Corp.
The company said the ultimate goal of China's lunar expeditions is to lay the scientific and technological foundations for manned missions to Mars.

In typical Chinese fashion, the very first hint of a possible landing date for the lander/rover comes from...one passing sentence of a certain insider on a Chinese forum.
May 17 it looks like it is.

I received the message from two independent sources in China, that landing is planned for May 15th and exploration by rover will start on May 22nd.

Thanks for the heads-up; I'll keep an eye out for it!

Hmm, apparently the entire spacecraft complex will head for atmospheric entry, the orbiter will perform a divert maneuver to go back into orbit following entry module separation. Risky.

Yes, but note it's doing so at close to apoaeron in its very elliptical orbit (27700 km): it will take the stack around 5h to fall down to periaeron, whether it be the 50 km needed for the capsule to enter the atmosphere or the safe 265 km for the orbiter. Too lazy to calculate the dV needed for such a maneuver, but I suspect it's not much. Far less risky than MOI.

Why do you think that? I see a standard entry.
The only strange part is cruise stage being below the landing capsule.
