This original 古风 song enters a fifth-watch courtyard where an open carved birdcage keeps the shape of someone absent. A pale feather rests on moss, bamboo leaves stir beyond the eaves, and a soft sheng breath lets the moonlight feel close without becoming theatrical.
The song moves from remembering the cage's shared past to leaving its door unlatched for whatever return the night may still carry:
月入闲笼不入帷
空枝犹待旧禽归
且将笼扉向夜开
Listen late at night, while reading classical poetry, or before dawn when you want a quiet ritual of distance, patience, and release.
