The photos transmitted by the Viking 2 lander and those taken by the Chinese rover show quite different landscapes. They do not corroborate each other, also they should look similar, as long as they present the same Utopia Planitia. So, there exist no mutual independent confirmation of landings in the above mention plain, up to the present moment.
"Utopia Planitia is a large plain within Utopia, the largest recognized impact basin on Mars and in the Solar System with an estimated diameter of 3300 km. It is the Martian region where the Viking 2 lander touched down and began exploring on September 3, 1976, and the Zhurong rover touched down on 14 May, 2021, as a part of the Tianwen-1 mission."

Utopia Planitia. Image taken by Viking 2 US Lander.
"The first photograph, a black and white image, was taken by an obstacle avoidance camera installed in front of the Mars rover. The image shows that a ramp on the lander has been extended to the surface of Mars. The terrain of the rover's forward direction is clearly visible in the image, and the horizon of Mars appears curved due to the wide-angle lens.
The second image, a color photo, was taken by the navigation camera fitted to the rear of the rover. The rover's solar panels and antenna are seen unfolded, and the red soil and rocks on the Martian surface are clearly visible in the image."

-1Stack Exchange questions need to be questions. This is a conspiracy theory-pushing argument only pretending to be a question. "They do not corroborate each other, also they should look similar, as long as they present the same Utopia Planitia. So, there exist no mutual independent confirmation of landings in the above mention plain, up to the present moment." You can't use Stack Exchange questions to "announce things" or push theories. Can you edit your post and remove the part I've quoted and simply ask a question? Otherwise this may be heavily down voted and/or closed. $\endgroup$
