Looking down at human nature is like standing on a watchtower where history and reality intertwine. In life, we are often confused by appearances, but we don't know that there are undercurrents surging beneath the calm. Don't underestimate the darkness in people's hearts. It may be hidden in the trivialities of daily life and show its fangs when conflicts arise. It may also lurk behind a seemingly friendly face and deliver a fatal blow at a critical moment. The darkness is like a bottomless abyss, swallowing up conscience and warmth. It always reminds us that to understand human nature, we cannot just look at the surface, but need to stay awake at all times.
