I m surprise this species can t be found in the book "the bird of Hong Kong and South China" nore the field guide to the Birds  of China (Oxford university)

It is mentioned in both books, indeed not as a species but as a subspecies of Blyth's Leaf Warbler (see text). It is now a separate species, Hartert's Leaf Warbler - Phylloscopus goodsoni.
