What does it mean to give away a white paper lamp?

"Send away a white lamp" is a common figurative expression, which is used to describe the reaction or touch caused by a person's departure when he leaves. This metaphor comes from the traditional folk art form in ancient China. The lanterns pasted with white paper have no bright light, so people regard it as a symbol when they bid farewell, expressing that "although the people who left were not particularly versatile, they left deep feelings and memories". "Give People a White Paper Lamp" conveys a simple and true emotion, and expresses deep nostalgia and gratitude for that person when leaving.
