Literature Reference: 南山有高树，花叶何衰衰。上有凤皇巢，凤皇乳且栖。四旁多长枝，群鸟所托依。黄鹄据其高，众鸟接其卑。不知何山鸟，羽毛有光辉。飞飞择所处，正得众所希。上承凤皇恩，自期永不衰。—— 《南山有高树行赠李宗闵》 On the southern mountain stands a tall tree, its flowers and leaves swaying sadly. Above, a phoenix nests, nurturing its young. The branches stretch long, supporting the birds. The swan occupies the high perch, while the other birds gather below. A bird from an unknown mountain, its feathers radiant, flies and chooses its place, fulfilling the hopes of all. It receives the phoenix's grace, vowing never to decline. — From 'A Tall Tree on the Southern Mountain, Presented to Li Zongmin'.
