Psychological knowledge: cause poor eyesight, and judge the "uphill and downhill" of the strange slope by feeling. The stone pillars of the strange slope are inclined, and the craftsmen specially decorated the ground at the entrance of the "downhill" to create a ground on the left that is higher than the ground on the right, and the visual error is greater!
Strange slope pavement is dirt road, not reinforced concrete pavement, nor asphalt pavement, because reinforced concrete pavement and asphalt pavement are very flat, you can judge which section of strange slope is high and which section is low with naked eyes (strange slope pavement is not a straight line), and the statue of strange slope is not horizontal.
Physical knowledge: whether there is a slope is judged by the direction of gravity, not by reference objects (stone pillars in the slope, the sky, the opposite mountain). The direction of gravity is vertical downward (can be judged by a vertical line).
