Which version of Li Bai's biography is good?

I think the version choice of Li Bai's biography varies from person to person, and there is no absolute difference between good and bad. The Collection of Li Hanlin, published in Xichun period of Southern Song Dynasty, is the earliest extant collection of Li Bai's works, and it is also the version closest to Li Bai's own works. Selected Poems of Li Bai published by People's Literature Publishing House has extensive selections and detailed annotations, which is of great help to understand Li Bai's poems and songs. New Notes on Selected Poems of Li Bai, published by People's Literature Publishing House, is a relatively new edition with concise notes and suitable for beginners.
