About me
Hi, I'm Yixin (逸欣)
Also Rita · 北冥 on other platforms
I work on types of problems, not just domains — especially where complexity and uncertainty meet.
Problem solver & thinker
I'm a problem solver and a thinker 🧩: I like taking problems apart, and I'm happy to stay a while inside complexity and uncertainty, slowly working out how the world actually runs 🌍.
Living at the intersections
My background is a bit of a mix — mathematics, law, data, AI. Not because I couldn't decide, but because I'm deeply curious about many disciplines, and I keep looking for the places where they intersect: where a method from one field quietly solves a problem in another ✨.
Sharing & keeping records
I also like to put things into words. This site is where I share what I've learned and keep a record of what I've tried — the attempts that worked, the ones that failed, and the ones I abandoned halfway. You can find me on other platforms too; the ways in are at the bottom of this page 👇
💼 I’ve worked at a startup in China, and now I work at a large corporate in Sweden. The first taught me to move fast with very little; the second is showing me how change really happens at scale — through people, process and a lot of patience. Wherever I am, I care about connecting abstract ideas with real constraints 🔗.

How this site works
🎯 Welcome to my coordinate system
I record my experiences and feelings by drawing a coordinate system and marking projection points on it. Right now it has four axes, and each one is a way I reach out to the world. Every piece I write marks one projection point 📍 — a certain time, a certain place, a certain dimension.
I don't intend to define myself by any single identity, or to tell the whole story at once. You're welcome to pull up a seat and listen 🧐
X-axis · Temporarily Living in the World
I don’t settle down, but I love to stay a while. Travel runs on itineraries; living somewhere runs on instinct — I’m mostly the latter.
I usually live in a place for a year or so: picking up its rhythm, trying to fit in, learning to follow the small talk on the street and getting used to the signs. Then every two or three years I move to another country or region, measuring the world slowly.
I treat the world as a giant amusement park 🎡. I take my time, and write a few things down along the way.
Y-axis · Character Cards
In this world I can swap in a new character card and step on stage at any moment: 🐂 office worker, 🎓 student abroad, 👧 daughter, 🐾 pet parent, 🥡 takeout regular, 🗣️ language bungee-jumper…
Switching identities is no big deal — I never planned to play just one life anyway.
This axis records how I play, how I switch, and how all that playing and switching turned me into who I am now.
Z-axis · Me in the Mirror
As a Gemini and an ENTP, I know I change fast. My state follows my surroundings; one small gust of wind and I become someone else.
I want to record the me in the mirror at every stage: carefree, confused, clear-headed, headstrong — and tougher than I thought.
Not to sum anything up. Just to understand myself through the changes — call it a practice in looking inward 🪞.
K-axis · Knowledge Forest
I want to learn too many things, so my path has run a little wild. I never sorted the disciplines out properly, and what I write is quite a mix.
This is a forest grown on its own by a cross-jumping brain. It is messy, but you might find some shade.
I like the name “knowledge forest”. No guaranteed sense of direction, but the view is pretty good 🌳.
📌 This coordinate system will keep being drawn. I will mark more moments, more roles and more thoughts here.
Start from any point, or pick one axis and follow it.
Welcome aboard — and feel free to get lost 🧭
