The content of these murals is quite simple; in the early ones, it depicts a solitary figure traversing deserts, lakes, and mountains, seemingly in search of something.
In the background of these murals, there are vague lines, resembling a humanoid figure or some kind of special pattern.
In the later murals, followers appear, tracing behind the figure.
At this time, the dense lines in the background appear to exhibit some sort of 'activity' trend.
Some lines stand up, forming ambiguous and simplistic humanoid shapes, as if they were some kind of 'person.'
He Ao looked back at the previous murals; indeed, these shapes were the earlier background lines.
In the previous murals, these lines lay there, resembling dead bodies one after another.
Yet, in the later murals, they 'came to life.'
