This collection of retrospective essays is a book of warmth and reflection by Lu Xun. The included "From Baicao Garden to Sanwei Bookstore" recalls the freedom of childhood and the boring bookstore, full of innocence and cherishment; "Mr. Fujino" expresses gratitude to his mentor, but also implicitly criticizes the numbness of the Chinese people; "A Chang and "The Classic of Mountains and Seas" depicts the kindness of a low-level nanny. The text is both tender and sharp, with reflections on society hidden in the plain narrative. It is a precious text for understanding Lu Xun's early experiences and ideological context.
