Scott Manley's excellent new video China's Mars Rover Zhurong Has Completed Its Primary Mission, Reaches New Milestone is chock-full of space-sleuthing goodies and interesting information about the mission, its spacecraft, and some of its engineers.

Below is a screenshot of the Tianwen-1 lander. While the context is the speculation that post-landing remaining fuel was spent by actually firing thrusters on each side resulting in the dipolar bright spots seen from orbit, I noticed that next to the Chinese flag there are some cartoon-like characters.

Question: Who are these cartoon-like characters displayed on the side of the Tianwen-1 lander?
