Zhu Kerou is the author credited with the First Fragrance Notes (Diyi Xiang Biji). Public information about his life is very limited: his English name, nationality, and dates of birth and death cannot be verified at present, and only one work is listed under his name in our records. On the available evidence, this work is classified as a classic, and it is the main window through which Zhu Kerou's writing can be approached. The title itself suggests a notebook-style approach, generally implying that observations, impressions, and reflections are recorded in the form of miscellaneous jottings, with a relatively free style that combines information with readability. Because the sources are insufficient, it is not possible at present to confirm when or under what circumstances the book was written or what it contains in detail, nor is it possible to assess Zhu Kerou's standing and influence in literary history or related fields. Readers who wish to know this author through the notebook work should rely on what the original text presents and remain cautious about the gaps in the available material.
