Literature Reference: The deer are calling, eating the wild celery. I have distinguished guests, playing the zither and the qin. Playing the zither and the qin, the music is harmonious and profound. I have fine wine to delight the hearts of my guests. I have exquisite dishes to delight the stomachs of my guests. I have a lush marsh to delight the eyes of my guests.
