THE LATEST LETTER · OCT 27, 2026
Kefei introduces a new way to explore Koffeemocha through a question, a topic, a remembered passage, or a connected reading path.
01 / FROM THE NOTEBOOK
↗An autumn conversation about a young mathematics tutor prompts Kefei to reconsider how parents pass on experience. Advice can compress decades of choices, hesitation, help, and luck into a conclusion, leaving children without the steps that made it convincing.
↗A bowl of bouillabaisse in Marseille becomes an encounter with another way of living. A waiter’s explanation, Sharon’s hands, and the knowledge carried through an everyday meal matter as much as the destination.
↗In the reconstructed bedroom at Saint-Paul-de-Mausole, a quiet window onto the garden creates an unexpected sense of spaciousness. A visiting tour group changes that feeling without changing the room.
02 / A PLACE TO BEGIN
You don’t have to read everything.
Start with the question you’re living.
Read across career pivots, changing identities, and the work of giving a second chapter a useful form.

↗At the Mer de Glace, the ice cave’s apparent permanence gives way to a different reality: a moving glacier requires a newly carved entrance each season. Machinery and protective coverings become part of the story.
↗A transfer day becomes an unexpected invitation into Toulouse’s evening life. Music, runners, volunteers, and a cheering crowd interrupt a carefully planned route back to the hotel.

From structures and cloud systems
to a life with more room to notice.
Kefei’s journey began in Shanghai, continued through structural engineering and cloud technology in the United States, and took a new turn in 2023. After retiring, he and his wife moved from California to New York to be closer to their grandchildren.
Koffeemocha brings that experience to essays about family, travel, work, and the choices that shape a changing life. It asks what to carry forward, what to reconsider, and how to stay open to what comes next.
