Literature Reference: The poem 'Bamboo' by Cui Ya: 'Taking the creek breeze and not letting it go, planting bamboo around the windows and courtyards. Inviting a wild guest to be a neighbor, watching the mountain birds enter the city. The quiet courtyard alone is startled by the early autumn air, the small door deeply opens towards the green shade. Who pities the emerald color and cold shadow, quietly falling into the teacup and wine cup.'
