Chen Ke paused at Fountain Square, surveying the entire street, attempting to establish simple visual landmarks.
He drew a line in his mind and placed the fountain as a central point, marking it in the middle of the line.
Then, he strolled with the crowd, observing the buildings on either side of the street, remembering the tallest ones.
Next, he quickly scanned the entire street again, memorizing the general color tones, and used some exceptionally bright shops as nodes, dividing the street into sections based on colors.
Soon, he divided the entire street into five major nodes with landmarks labeled "church," "bell tower," "office building," "mall," and "fountain."
He then divided these five nodes into four sections colored white, blue, red, and green.
Following that, he used the fountain as an anchor point, which would allow him to maintain a general sense of relative position in his mind no matter how he moved.
