Methods: 1. Huma uses dual rhetoric to "Yueniao", "Yi" to "Nest" and "Beifeng" to "Nanzhi". 2. Huma "Yi" and Yueniao "Nest" endowed them with feelings and used anthropomorphic techniques.
Appreciation: Poems give "Huma" and "Yueniao" human feelings, and express the thoughts and feelings that leaves fall back to their roots and miss their homeland.
