"Tu's poems," she said, "are known for their workmanship and artistic refinement, while Li's poems are known for their freedom and naturalness of expression. I prefer the vivacity of Li Po to the severity of Tu Fu." "Tu Fu is the acknowledged king of poets," said I, "and he is taken by most people as their model. Why do you prefer Li Po?" "Of course," said she, "as for perfection of form and maturity of thought, Tu is the undisputed master, but Li Po's poems have the wayward charm of a nymph. His lines come naturally like falling flowers and flowing water, and are so much lovelier for their spontaneity. I am not saying that Tu is second to Li; only personally I feel, not that I love Tu less, but that I love Li more." "I say, I didn't know that you are a bosom friend of Li Po!" "I have still in my heart another poet, Po Chüyi, who is my first tutor as it were, and I have not been able to forget him."
