Literature Reference: 旧笋方辞箨，新莲未满房。林幽花晚发，地远草先长。抚枕愁华鬓，凭栏想故乡。—— 《宿荐福寺东池有怀故园因寄元校书》 The old bamboo shoots have just shed their sheaths, while the new lotus flowers have yet to fill the pond. The flowers bloom late in the secluded forest, and the grass grows early in the distant land. I lay my head on the pillow, lamenting my graying hair, and lean on the railing, thinking of my hometown.
